Dear Welder Series… why are there three holes on the axle brackets?

Dear Welder Series…

Hey DW
Hope all is well sir and you are having a good year so far.
A question came up in our shop this weekend and I am wondering if you could let me know the correct answer when time permits please!

The axle brackets on your parallel 4 link kits- the 3 holes on the rear for shock mounts- are the 3 holes used for initial ride height setup ONLY, or are they options to be used for future ride hide adjustments??

Great debate here on whether they are meant to be used adjusting the ride height whenever you want or if they are meant to be a ‘one time’ use during the chassis build.

Could you let me know the official response please? (I have a $100 wager on this)

Regards,
John

Dear John…

Hi, John.

DW suggested we give you the answer you want for a cut of the action… (Just kidding…)

My “official” answer is: Nobody loses this bet.

Usually the 3 holes are used as a lower mounting point for coil-overs or ShockWaves. They can be used as shock mounts when conventional air bags are used, but my first thought is for coil-over suspension. That’s the basis for my answer.

Coil-overs and ShockWaves have a “designed ride height”. https://welderseries.com/tech/tech-sharing/coil-over-mounting-offset/. We feel a custom vehicle should be built with the suspension at ride height. https://www.welderseries.com/Right-Height-Vehicle-Set-Up-Tool-p83035424. Physical constraints might dictate the (ideal) location for the upper coil-over mount. The 3 axle bracket holes will give some flexibility to the upper mounting hole location, since the (fixed) coil-over ride height is important to the vehicle ride height. So the wager winner is the initial ride height setup only… maybe…

The 3 holes allow for future adjustments that might involve different coil-overs, different wheel/tire combinations, or a different “look” desired for display at a car show. I have moved the lower coil-over up a hole when going on a vacation trip with a “kitchen sink” in the trunk. So the wager winner winner is the adjustable person… maybe…

I hope you two have a laugh over this and save your money for Welder Series parts.

Thanks for writing. It’s been fun answering.

Dear Welder Series…

Thank you very much Mr. Horton

As always I appreciate your responses. (I will selectively edit parts of your response and attempt to cut you guys in as I might lose now)

Another question if I may- wouldn’t adjusting up or down a hole as you suggested at the bottom throw off your driveline angles? Or would the difference be minimal?

What brought this about is a wager on my Model A coupe- it rides a touch too high in the back & the wager was whether you can drop it a hole and not throw everything off. 

Thanks, John.

Dear John…
Raising or lowering the rear by 1” on a Model A will change the driveline angle by less than 1/2 of 1 degree. I’d consider this minimal and should not cause a problem… unless the driveline angle is already borderline. Lowering the rear could be offset by shimming the transmission mount.

Dear Welder Series…

Well sir I appreciate your insight very much regardless of the $100 I just lost haha

Thank you very much regardless

John.

Dear Welder Series…four bar bars – do they need jam nuts?

Dear Welder Series…
I have a couple questions about your 4 link kit. With the adjuster just on one end, wouldn’t it be best to just forget the jam nut? With a rubber boot to keep the dirt out, wouldn’t this let the bar “twist” and prevent binding? I’d have thought that the nut would work loose anyway as the adjuster attempted to loosen or tighten when you go over a bump with one wheel.

Also, I assume your adjusters and bars are a mild steel. How do I stop them from rusting after welding? Do you recommend plating? I would paint the bars etc but I’m unsure about the threaded portions.

Thanks
Miles

Dear Miles…
Hi, Miles. For street use, the bushings have enough elasticity to absorb the twist and not loosen the jam nuts. Even lubricated, it’s likely that the threads in the mild steel bars and adjuster studs would wear and either fail or have to be replaced periodically.

Thread the adjusters into the bars without the jam nuts to keep the threads clean, or just mask off the portion of the thread that will go into the bar.

Thanks for your interest in Welder Series parts.

Dear Welder Series… center section for 67-72 C10?

Dear Welder Series…
Any idea whether the center section will work with a 67-72 C10, and do any of the trans mounts fit a 4L80E?

Thanks,
Russ

Dear Russ…
Thanks for this note, Russell.  

Could you give me your frame’s outside and inside widths (driver’s side to passenger’s side) at the transmission insulator?  

…and the frame rail channel height at that point? (The actual frame size, not the height from the ground.)

I’ll see how the center section looks in those dimensions and get back to you.

Paul Horton

Dear Welder Series…
Thanks Paul,

I’ve got the following:

Outside frame rail width:  34-1/8″
Inside frame rail top:  29.5″
Inside frame rail bottom:  29″
Frame rail height:  6″

Dear Russ…
The center section will be snug but fine if the rails are boxed corner-to-corner off of the upper flange. If the plates are “step boxed” it will give extra space for a frame mounted booster.

This is based on how the curved lower tubes transition to the boxing plates.

I hope this info helps with your planning.

Dear Welder Series… 1976 Datsun 260Z Mustang II

Dear Welder Series… 
I’m customizing a 1976 Datsun 260Z for a client. It has an all aluminum Mustang Cobra 32V V8 up front and a narrowed 9″ triangulated 4 link setup in the rear. I want to put something like your Mustang II IFS kit on the front and get rid of the struts so that I can mount a wider torque thrust II wheel to match that back.

The frame rails have a lip that sticks out a little on the bottom facing out, and the width from that outside edge to outside edge is 32″. They are smooth on the inside.

Do you have something that will work for me? If you do, can you send me other dimensions so that I can measure up to make sure everything will fit under the original fenders?

Any help would be appreciated,

Thanks.

Brett

Dear Brett…
Our Mustang II coil spring kits are designed to be installed in almost any frame. What measurement do you want between the wheel mounting surfaces? (Where the wheels are against the rotors…)

What diameter tire will you use on the front?

With the frame at ride height, what is the distance from the ground to the bottom of the frame at the spindle location?

As above to the top of the frame?

With this info, I’ll be able to tell you about installation issues you might run into and suggest ways around them, if necessary.

Thanks for looking at Welder Series parts.

Paul Horton

Dear Welder Series…
Thanks for getting back to me.

There are a lot of questions there that I don’t have the answers to yet.

I’ve just finished the back end of the car, so let me measure the front up this weekend and I will get back to you.

Cheers,

Brett.

Dear Brett…
Thanks, Brett. I might be slower getting back to you for the next week or so… There will be days when I’m out of internet access. I’ll try not to keep you off the road too long…

Paul Horton

Dear Welder Series…
Here are those numbers!

What measurement do you want between the wheel mounting surfaces? 54″

What diameter tire will you use on the front? Don’t know yet, but to match the rear the center of the front spindle will need to be 12 3/8″ from the ground.

With the frame at ride height, what is the distance from the ground to the bottom of the frame at the spindle location? 11″

As above to the top of the frame? 14″

This car is pretty low, so if we need to go up or down a little, I would prefer to go up a little on the ride height. We have a tri-4-link with coil overs on the back so we can always adjust the back up or down to match whatever the front ends up being.

Cheers,

Brett.

To Be Continued…

Dear Welder Series… Mustang II control arm holes

Dear Welder Series…
On the coil over shock crossmember it shows a 1/2 hole for the lower a-arm, the lower a-arm pivot bushing on my lower a-arm requires a hole 1 3/8 hole. Is that going to work on this crossmember??

Dear Len…
Len, the 1/2″ hole is stock Mustang II. Many aftermarket a-arms use a 5/8″ bolt and some spacers inside and on the back of the crossmember. Depending on the arrangement of your spacer(s) and bolts, the 1/2″ holes might only have to be drilled for the 5/8″ bolt. If the spacer is 1 piece (on the driver and passenger sides), it can either be cut in 2 to put one section between the front and rear crossmember plates and the other piece on the rear side of the crossmember. Or the rear hole can be opened up to the spacer diameter and leave the spacer as 1 piece.

I hope this answers your question.

Dear Welder Series… 35-40 Rear Boxing Plates?

Dear Welder Series…
Do you have any frame repair kits for the rear wheel area for a 39 Ford stock chassis for restoration.
Mainly need the area at the axel hump behind the rear wheel

Bill

Dear Bill…
Bill, we have boxing plates for the rear half of the 1935 – 40 Ford frame. These might help to reinforce the stock rails, if they are still part of the frame. https://www.welderseries.com/Boxing-Plates-1935-40-Ford-p50906470 shows the whole kit (front and rear halves), but the rear plates can be purchased on their own. Part #354002, $50.00 each.

Do you think  this would fix the problem?

Paul

Dear Welder Series… custom transmission mount

Dear Welder Series…
Paul and Dorothy,
Ordered some parts from you all a couple of weeks ago to make a trans mount for a 1990 corvette trans that I am putting in my 56 Chevy pickup. Paul even call the day after I ordered to make sure I ordered the correct parts. Thanks, I appreciate that. Paul said send some pics when I got it made and on the truck so here it goes.
Dale

Dale cherry picked some brackets from other transmission mount kits and made his own. He used our 350 adapter plate, a shock mount plate, and a little tab that normally welds into the adapter plate, but he only used one side of it. You’ll understand when you see the pictures.

This is one of the reasons Welder Series is here. Thanks for being creative, Dale.

Dear Welder Series… 1953 Ford parts list?

Dear Welder Series…
I am looking for help with my 1953 Ford build.
I have purchased a 1993 LS1 motor, a 700 trans and a 12 bolt rear end I am trying to fit in the truck. The wheels I will be running are 30″ on the outside, 10 3/4″ wide with a 6 7/8 offset from the back of the rim. My goal is to set the bumpers and running boards on the ground with a full air ride. Is there a chance you could specify what I will need to purchase from your catalog to get all my frame welding going? As it stands right know I have pulled all the suspension out of the truck and it is just sitting on the frame now. Would love to order everything for Christmas. Thank you for your time and please feel free to call with any other questions you might have.
Keith

Dear Keith…
Keith, here are some links to kits for this build:
Choose a 60″ track width kit for your F100.
If you will use conventional air springs: http://www.welderseries.com/blog/online-store/category/mustang-ii-crossmember-kits/?sort=title
If you plan to use ShockWaves:

If you will use a power rack from a 79-92 T-Bird, order the relocation kit:

There are several different LS engine mount kits.  They are shown at http://www.welderseries.com/blog/online-store/ls1-motor-mounts/ .

For your 700 R4 transmission, here are 2 options:
A simple crosmember and drop-out saddle (check out the “welded” version):

Or a tubular center section (with the 700R4 trans mount option):

For either of the above, use transmission mount insulator

If your 12 bolt rear end has the ears for the triangulated GM links, you could use our rear kit:

We would add brackets if you will use conventional air springs.

 

The crossmember shown below can be used to mount the upper end of the ShockWave (with 5/8″ hardware), or shocks with 7/16″ upper eyes.

If you plan to use a parallel rear 4-link, here are the kit pages:

For ShockWaves:


Use the rear crossmember with 5/8″ bolts.
With shockWaves on either the triangulated or the parallel kit, use the bolt kit here:

I hope this list helps.  Please write or call on our toll-free line, 1-888-648-2150, if you want more details.

Dear Welder Series… Mustang II coil over length question

Dear Welder Series…
Hi Paul,
I recently bought a coil over MII kit from you. I see a recommended ride height for the coil overs, but how about extended and collapsed length, or shock travel length?

Thanks
Matt

Dear Matt…
Matt, we define a coil-over’s ride height as eye center to center compressed 1/3 of the stroke from fully extended. For example, a coil-over with an extended dimension of 13″ and a compressed dimension of 10″ would have a designed ride height of 12″. Similarly, a coil-over with an extended dimension of 14-1/2″ c-c and a compressed dimension of 10″ would have a designed ride height of 13″. A shock with 3″ of travel will be fine for a MII front end. Shocks with longer stroke have the potential for a better ride, but only if the chassis is built so nothing tops or bottoms out with the extra travel.

I hope this helps with your selection.

Dear Welder Series… 1957 GMC truck four link?

Dear Welder Series…
Hi, I contacted you last year before Christmas sometime and was going to order up a rear 4 link with air bag brackets. Since then things have changed and now I will be doing the same thing but with a smaller axle. It is the gm 8.5″ from an S10. The axle tube dimension is less than what your brackets are cut for. Do you have a different axle bracket to fit the smaller axle tube diameter? Or do you have a suggestion for my problem?
thanks,
Dennis

Dear Dennis…
Builders have used a short length of tubing, 3″ O.D. and the same I.D. as your axle tube, as a bushing. Split the tube into 2 “C” halves. This will make up the difference in the axle to bracket diameter. It will also spread the load over a wider area for more strength.

Thanks for asking, Dennis.

Dear Welder Series…
Hi Paul,

thanks for getting back so soon. This is going to be installed on a 57 GMC truck. I am thinking the bars should be sort of parallel with the road at ride height, which means the lower bar will be below the frame quite a bit. Do you make a frame bracket for these trucks?
thanks,
Dennis
Dear Dennis…
I have a similar bracket that was designed for the Ford F1 truck. One bar mounts just above the bottom of the frame rail and the other is lower. Will check it out when I get a few minutes.

Thanks for asking.

Paul
