Dear Welder Series…
Hi, I just received my 4-link kit and everything looks great! I have a ’71 chevy C10 truck I would like to convert to Mustang II front end. It’s my understanding my truck has a stock track width of 65.8″ (with stock wheels and tires). Should the measurement be taken hub-to-hub? I noticed the widest kit you offer is 60″ Any suggestions? Thanks for any info.
Thanks for your comments on the rear 4-link, Brandon. It’s a lot of work putting a Mustang II in your truck. 60″ is the widest track we have. To get out to 65/66″ (assuming you are comfortable doing the frame modifications required), get the 60″ kit and assemble it with your control arms, spindles, brakes, wheels/tires, and rack. Next, position it under your truck to determine exactly how much wider you want it. Make the crossmember this much wider in the center. A special rack can be ordered from Maval Mfg, http://www.mavalgear.com/unisteer.html.
Thanks for looking at Welder Series parts.
Dear Welder Series…
So the only way to fit the kit is with a completely assembled front end? Where I found the track width info they said with stock wheels and tires, so I’m wondering if it’s the overall width? The frame rails in the front are only about 28″wide. I don’t have any issue with the fab on the frame or cross member. I just didn’t want to have to buy a complete hub-to-hub kit when I’m so far from completion.
I understand your plan, Brandon. Here is some math for you to consider: A stock Mustang II track width is 56-1/2″ using stock rotors. The lower control arm pivot bolts are 22-1/4″ c-c on our 56″ kit. The distance from the lower arm pivot hole to the rotor wheel mounting surface is, therefore, 17-1/8″. (56.5 – 22.25) / 2 = 17.125 If you know how much the brake kit you plan to use differs from a stock MII location, you could calculate how much to add to the crossmember if stock-dimension control arms are used. This would probably be close enough, since the fenders are so large and +/- 1/2″ might not be a problem.
You might want to read through the installation instructions here (for the mustang II crossmember kit) or here (for the mustang II coil-over crossmember kit) to get an idea of the frame work required.
I hope this helps.
