Dear Welder Series… 1965 Lincoln Mustang II?

Dear Welder Series…
Would you have a Mustang 2 crossmember solution for my problem. My frame rails curve inward and gets narrow at the crossmember/motor mount location so I would require a crossmember of about 24” wide between the car’s frame. The problem is my track width is 62”. Available Mustang 2 crossmember kits that measure 24” typically have a track width of only about 56”.  
Do you have any ideas on how I can retrofit a Mustang 2 crossmember kit into my ‘65 Lincoln short of having to replace the frame with straight pieces to get rid of narrow the section? Would longer upper & lower control arms and a longer top hat be a good option for providing a wider track for a narrow crossmember?
Please Advise, Thanks!Gilbert

Dear Gilbert…
I think you should consider adding straight sections of plate steel to make the frame wider in the crossmember/upper tower area. This would be top, bottom and outside pieces to give an outside dimension of 35 – 36”. Then trim the stock frame inside the new pieces and add the fourth side. Now the crossmember can be mounted under and inside the frame and the towers can weld on top and outside. There are some pictures in the Mustang II section of our website showing frame pieces in stock frames. It is not an easy job.
The longer control arms would require a special rack and this could start a whole new set of things to adapt to.
Thanks for asking us about this.Paul Horton

Dear Welder Series…
Thanks for the recommendation and quick response! You confirmed what I was dreading, the frame has to be modified. 
I apologize if this sounds ignorant but to exhaust the other option, could longer tie rods/ends (approximately 3” longer each side) be used on the steering rack to accommodate the longer control arms? Or would this throw off other steering parameters?
Appreciate the advice,Gilbert

Dear Welder Series… 1951 Merc Mustang II?

Dear Welder Series…
Hi Paul
Building a 51 Merc do you have know which width will work best, also I don’t see it listed but do you have an already or mostly welded kit?
Thanks

Dear Jeremy…
Jeremy, if your Mercury is a pickup (M1), use our F1 Mustang II kit or our 60-1/2” custom fit kit. You can also use our kits for coil-overs. If your Mercury is a passenger car, it will be necessary to modify the front frame section to install the Mustang II crossmember. Check the thumbnail pics on our website and read our instruction sheets while you look at your car’s frame.

Dear Welder Series… 1957 F100 Mustang II

Dear Welder Series…
I’m building a 1957 F100, and would like to use some of your products, but I have a few questions.

I want to use your mustang 2 crossmember with coil overs, but I’m wanting to set the ride height of the truck pretty low, so clearance for wheels in turning becomes a concern. Would I be better off using your middle width m2 crossmember, and modify my frame, to pull the wheels in a bit? I also don’t have the wheels I’m planning to use, as I’m not quite sure what to order on backspacing. Any suggestions for that?

Thanks,
Shane

Dear Shane…
Hi, Shane. Thanks for asking but I’m not sure that I’ll be much help. Back when we built customer projects, we used 60-1/2” kits and 7” wide wheels. There was always lots of clearance.

Because you don’t have the wheels/tires, I’d suggest working on other areas of the project until you have had time to check out more vehicles at events to see what’s been used and how that was managed.

Thanks for looking at Welder Series parts.

Dear Welder Series… 1949 International kb1 Mustang II

Dear Welder Series…
I have a 1949 international kb1. I would like to use coil springs and the mustang 2. I think it would take the 60 inch track. Is this correct? What would be the total cost shipped to Winnipeg? Do you offer welding of the basic member? Thanks

Dear Paul,
Paul, There are 2 frames for KB1’s, according to my info, 28” and 30” outside width. With either of these frames, I’d widen the frame outside dimension by adding tubing so the 60” kit has more frame surface to weld to. Read through the installation sheets here and I think you’ll see what I mean. (30” frame outside doesn’t give any surface on top of the frame for the upper tower to weld to in the 60″ kit.)

Here is a link to the web store page for the Mustang II:

There are other parts there that you might need, too, and some videos.

The 60-1/2” kit, welded, including freight and sales tax would total C$346.50.  (That’s Canadian Dollars…)

Dear Welder Series… 1953 Buick Mustang II?

Dear Welder Series…
Hi! I’m building a 53 Buick Special in Memphis and was looking for some info on Mustang 2 IFS. I’d like to build my own setup but not really sure where to begin! Any info would be greatly appreciated and any parts to get me going I would definitely purchase! Thanks for your time!

Dear Mustang II In Memphis…
Thanks for looking at the Welder Series site and asking about our parts for your project.  

The easiest way (and it’s not easy…) is to cut off the stock frame at the firewall and use rectangular tubing as new front frame rails. The Mustang II crossmember and towers will mount to them. It will be necessary to fab mounts to support the rad (cradle) and front end sheet metal. There are several pictures on our website where builders have done this. See them at:

We want to help you enjoy this build.

Dear Welder Series… 1950 Chev Pickup Mustang II?

Dear Welder Series…
Hi! I have a 1950 Chevy 3100 pickup. I decided that I want to run with the mustang II ifs. I won’t be able to buy everything all at once, so I want to start with the crossmember. I want to run bags, so it will sit on the ground. Can you tell me what crossmember is best? Thank you.

Dear Juan…
If you are planning to use conventional bags, use this version: 

 

The airbag people have mounting brackets to fit in the upper towers.

If you plan to use ShockWaves, use this version:

 

If you click on the product you can view some pictures of airbags being used with this crossmember.

Thanks for looking at Welder Series parts for your pickup, Juan.

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.

Dear Welder Series… JeepRod Mustang II?

Dear Welder Series…
I am building an army willys jeeprod and I plan to put a mustang II suspension in front of grill. 30 1/2″ outside frame to outside frame. Money is limited so what would a complete kit cost me. I could not find any complete kits on your site.

Thanks and God bless.

Dear Pastor Ron…
Ron, we sell only the crossmember kit and a disc brake kit, not a hub-to-hub kit. Several of our dealers offer complete kits using our crossmember. They are listed at https://www.welderseries.com/more/dealers-builders/. The 56″ kit will likely need some frame trimming for coil spring clearance.

Thanks for looking at Welder Series parts for your project.

Dear Welder Series… 1973 Ford Truck Mustang II?

I have a 1973 F100 that I really want to lower, I know with the I beam set up, I won't be able to lower the truck as low as I want to. On your Mustang 2 parts for the front end do you think I would be able to weld in one of your kits and make it work?

Dear Welder Series… Mustang II for 1950 Studebaker?

Dear Welder Series…
What measurements or info is required so you might be able to tell me which mustang ll kit I would need to use in a 1950 Studebaker champion 2 dr coupe and a starlite coupe. Would a 1948 starlite use the same kit as the 50? thnx

Dear Roger…
Roger, there are two measurements to consider when selecting a Welder Series Mustang II kit:  the track width that you want and the outside frame width in the crossmember area.
Track width is the rotor wheel mounting surface to surface dimension. Welder Series makes 3 widths: stock (56″), and 2″ and 4″ wider (58″ & 60″). These are nominal dimensions. With stock, 4-bolt MII rotors the actual track width would be 1/2″ wider than our listed spec, but the final track width is dependent on the control arms, wheels, and brake system used. An easy way to estimate the stock track width is to measure tire tread center to center.
The outside frame width is less critical than track width, but is a consideration. Our 56″ kit likes a frame o.d. of 26″ – 30″.  The 58″ kit likes 28 – 32″ and the 60″ kit likes 30 – 34″. If the frame doesn’t correspond to these dimensions, there are work-arounds that we can suggest.

I hope this helps with your planning. Thanks for asking.

Dear Welder Series… 1974 Triumph Spitfire Mustang II?

I have a 1974 triumph spitfire with a sbc, it has a frame width of 19" and a track width of 49.5", i would like to install your mustang 2 crossmember do you see any reason why your 56" would not work if I narrow it?

Dear Welder Series… 1951 Chevy Mustang II?

Dear Welder Series…
I want to start purchasing the parts to the Mustang II kit, I have a 51 Chevy Coupe. I was looking at this:

I have a couple questions.

  1. What track width do I select for that car? I’m probably going to run stock steel wheels and 640 Bias Ply tires.

2. When I do purchase the upper spring hat, will it allow me use air bags??

Dear Drew…
Thanks for looking at Welder Series parts, Drew. The 56″ track width is right for your Chev. The kit for stock-type springs will let you use air bags. The bag companies have a top hat looking adapter.
