      John, I suggest getting the 56-1/2″ kit and some narrow control arms. Mock up everything using a bar to hold the lower arm level, including the wheels and tires that you will use. This will require tacking some fill pieces to hold the upper mounts in place. Then roll the assembly under your Datsun and establish how much has to be cut from the middle of the crossmember to put the tires where you want them. A narrowed rack will be required.

    Hey Paul, I have a 1980 Chevy Luv Truck that I want to put a Mustang II front suspension into. I ended up with some Mustang II parts, that I would like to install in the truck. The truck has a 102.5 Wheelbase, 51.5 rear track width, and 51.75 front track width. I don’t know the distance across the frame rails yet, but I know you are going to need them. I have a few scattered Mustang II parts, originally for a 1950 Chevy. A Mustang II cross member, which is going to be way too wide, A arms, that are probably going to be too long, with spindles with rotors for disc brakes with Chevrolet bolt pattern, generic shocks and springs, and some QA-1 coil overs that I will have to find out what they will fit. I wanted to ask you if any of this will work, and purchase from you what I don’t have, to make something that will work.
    Thanks,
    Hal

    Hi DW, this may have been covered already, but here goes. I have a ’61 Falcon. Would your MII kit for the ’63-’65 fit?
    Thanks

    I am intrested in weather there are any problems putting the welder series coil over mustang setup under my full fended 34 fordoor
    any interference with fenders
    thanks Scott

    • DW says:

      Scott, the fender braces bolt to the frame where the upper towers for the control arms attaches. Usually, builders cut the fender braces and make brackets to bolt or weld them to the upper towers.

      There isn’t any interference between the Mustang II parts and the actual fenders.

      Thanks for looking at Welder Series parts for your project.

    Hello. I am building a custom frame with an OD of 30 inches. Do you make a mustang 2 front suspension with a 52 inch track that will fit it?

    Thanks Ken A

      • Ken says:

        Thanks for the reply. I haven’t started to assemble the frame just yet. And 26″ wide frame is no problem to build instead of 30″ wide. Could you list the all the parts I would need get the front suspension on wheels. It’s a small VW truck build going for a Rat rod look. So looking to build it on a buget. Thanks

    I’m looking to replace the original ford mustang 2 cross member that is currently in my Cobra Kit car with one of your coil over cross members. I will be upgrading the a-arms to original length tubular strut-less and installing coil over shocks.

    What coil over cross member would retain the original mustang 2 width/geometry.

      Hi, Nathan. I like International trucks but don’t know the track width or frame specs for the different models. We make kits for track widths of 56-1/2”, 58-1/2”, 60-1/2”, and 62-1/2”. We define track width as the dimension from wheel mounting surface to surface on the rotors. For a 56-1/2” track width, the easiest frame widths to work with are between 26 – 30” outside. As the track width increases by each 2” increment, the “easy” frame widths also increase by 2”. For frame widths larger or smaller than the “easy” widths, the frame can be stepped in or out to accommodate the crossmember and towers. There is some info about this at http://welderseries.com/-p51209443.

      Thanks for considering Welder Series parts for this project.

    Trying to find a set up for my 1956 international s100 frame. But not sure what kit I would need would also like to run Chevy wheels and brakes if that matters

    • Mark says:

      Edit. I just seen the comment before mine. If i were to measure distance of outer portions of the rail would that help to pin point which kit would work?

      • DW says:

        The kit you choose will be less a function of the width of the frame rails, than the desired track width. It’s easy to think of it like this: walking up to a car at a cruise night, it’s obvious if the tires are sticking out of the fenders 2″ each side, but nobody knows if the frame rails are the “correct” distance apart. We suggest mocking up the wheels and tires you’ll be using in the fenders, with the truck sitting at ride height. Measure the wheel mounting surface to wheel mounting surface, and that’s what we refer to as your track width.

  7. Jeremy Long says:

    Hi Paul
    Building a 51 Merc do you have know which width will work best, also I dont see it listed but do you have an already or mostly welded kit?

    Thanks

    • DW says:

      Hi Joseph. We don’t have a direct fit crossmember for your Falcon, but our 56″ kit would be the one to use if you’re fabricating the front frame section.

      Thanks,
      DW

    Hi, im looking for a 58 inch mustang 2 front suspension kit with cross member for a 1948 pontiac streamliner

  9. Mark Kanewske says:

    My name is mark I have a 66 nova I need a frame only not a kit I have a kit in it that just didn’t work do you sell frame only

    • DW says:

      I’ve come across this request and hope I can still help. Also saw you picture. Looks like a good start!

      The Mustang II crossmember to use depends on several things:
      – The track width you want. We refer to track width as the dimension from tire tread center to center. Stock Mustang II was 56-1/2” and we make crossmembers for this, 58-1/2”, 60-1/2”, and 62-1/2”.

      – The frame width. Generally speaking, the 56-1/2” kit “likes” a frame width of 26 – 30” outside. Add 2” to that for the other kits as they increase in width. For frames wider or narrower than ideal, there are workarounds.

      – The height of the frame relative to the height of the spindle. In general, the ideal height of the bottom of the frame at the crossmember would be the same height as the spindle, plus or minus 1” for stock spindles. Dropped spindles can be use to lower the frame 2” from that. Spindle height is relative to tire size and will be close to the tire’s radius minus 1/2”. Tire dimension charts are on many manufacturer’s websites.

      – The frame’s cross-section. A rectangular cross section is easiest to work with. When the frame, in the crossmember/upper tower area, is not rectangular, often a section of tubing can be put there. Other times, steel plate can be used to provide an area to weld the crossmember and towers. Channel frames can, and should, be boxed. Some other frames should be reinforced for strength.

      There are many pictures of Mustang II installations on our website. Look at them to see how builders have used our kits.

    Hi there! I have a difficult one.. I have a 1960 Opel Record. Frame rail is 24 1/2” outside to outside and the track width is 54” at best. Do you have anything that would work?
    Thank you so much!
    Becky Bliss

    • DW says:

      Hi, Becky.

      We suggest a way to put a Mustang II in vehicles with narrow frames and track widths a little further down this page. Scroll down through the comments and you’ll see a few builders who asked the same type of question as yours.

      If this info doesn’t help, please get back to me.

      Thanks for looking at Welder Series’ parts.
