Although the Mustang II is not the best layout for competition, it is a tried and true geometry for thousands of street rods and hundreds of thousands of highway miles. Many manufacturers have all of the parts needed (spindles, brakes, springs, sway bars, etc.) Of course, we hope you will use some Welder Series parts in your design.
The upper arm pivot points are shown as 29-1/2” apart. The stock upper arms adjust in slots, so this dimension is not absolute. It is a starting point, and one that can be used when the upper arms will use threaded adjusters to dial in the alignment.
The side view shows the upper arm pivot center line at the front, the center, and at the back. These dimensions will give the stock Mustang II anti-dive angle of 4 degrees.
Stock lower arms measure 13-1/4″ from the pivot bolt center-line to the center of the ball joint.
Several builders have made their own I.F.S. using Welder Series’ Mustang II crossmember parts
(143731, 143751 & 14307) and 21902 or VersaTabs (20493) for their upper arm and coil-over mounts. Upper and lower arms can be made using 108211 ball joint housings and Welder Series urethane bushings and adjusters.
Any chance you guys have an upper control arm mount for a mustang ii that instead of slots uses the gm style shims? I have installed dozens of mustang ii’s and have always despised the slot style adjusters. I have had several move, pop, go out of adjustment and one actually broke out the slot area. I have seen the gm style adjusters done and had a set designed but lost the cad files. Id be all over your kit if you had it.
Sorry, Craig, we don’t have a GM shim-style upper arm mount for the Mustang II arms. We appreciate suggestions like this.
Thanks for looking at Welder Series parts.
Can you give me an idea of what I will need (kit wise/cost wise) to install ifs front suspensions and four link coil over rear suspension for my 28 model A. How detailed are the instructions that come with them? This is all very new to me.
Mark, our Model ‘A’ Mustang II kit is at https://welderseries.ecwid.com/Model-A-Mustang-II-crossmember-kit-p51336531. The Classic Rods and More video on that page shows how to install it.
Our rear 4-link kit is at https://welderseries.ecwid.com/Model-A-Triangulated-Rear-Four-Link-Kit-p122517030. The installation sheets show where to weld the frame and axle brackets. We will get them added to the store.
Pricing is shown for each product in the store. Shipping cost is 10% of the order, minimum $15, maximum $60.
Thanks for looking at Welder Series parts.
I have an 83 caprice 8.8 with factory four link triangular suspension that I am trying to install in a 58 apache truck. Do you have kits for that? The 8.8 has factory four link attachments and would like to utilize them.
The https://welderseries.ecwid.com/Triangulated-Four-Link-Kit-for-8-8-or-GM-p51209601 kit works with Ford’s 8.8 rear end and GM’s triangulated rear end. Click on the main picture. This will let you see several more “installed” pics and the bars and brackets for the differential “ears”. The holes in the Welder Series brackets will have to be opened up to the same size as your stock bushings.
Hey guys which mustang ii kit fits on a 1962 ford falcon wagon? Thanks will be ordering one very soon..
Can you give me an idea of what I will need to install ifs front suspensions and four link rear suspension for a 1955 International Metro Stepvan
Gabe, basic research didn’t give me much to go on…
What track width do you want? This might depend on the wheel/tire planned.
What is the frame rail outside dimension at spindle location?
Will the bottom of the frame, at the spindle location, be higher, lower, or the same height as the spindle? By how much?
What are the frame rail cross section dimensions? e.g. 2×3, 2×4, etc.
This info will get us started on an answer.
Looking for a non mustang II front end for a 68 c10 pickup
Sorry Chris, we only do Mustang II crossmembers… I think Detroit Speed has some really nice options for your truck.
If i buy one of your crossmembers for my 67 nova could you guys notch out on the crossmember where the frame rails go,at extra cost of course.I would buy all of the materials to make contyol arms,nice stuff by the way
Please email Paul (firstname.lastname@example.org) to discuss this project.
Thanks for reaching out.
When setting anti-dive should the frame be set at the rake that it’s going to be on the street or with the frame flat and level?
Hi Bill, thanks for asking. It’s ideal to build the whole car at ride height, including setting up the suspension geometry.
Paul, thank you for this great resource. I’m looking into your weld together mustang II kits for the front end of a 70 vw bus as the parts, ride and brakes are all better. Is akerman angle something I need to be worried about?
Awesome products but I have a question? I am building a chassis for a v8 beetle and the dimension on the inside of the front rails is only 21-1/2″. Do you design or sell a crossmember kit that will work with these dimensions? The rail tubes are 2″ x 3″ Thanks Dave
David, what track width (tire centre to tire centre) do you want? We have some suggestions on our website. In the search box, type “narrow Mustang II”. I think this will help. If it creates more questions, please write or call us again.
do you have a setup i could use. im building a 37 ford and want to do ifs mustang 2 front and a 4 bar setup for rear. bagged front and rear also. thanks.
Hi Ken, thanks for your note. Your car would use our 56″ track width crossmember kit. If you’re wanting to use air bags, use the coil spring kit. If you’re using Shockwaves, use the kit for coil overs. Our universal four link would work great on your car too.
