I have a 95 ton dually chevy that I am planning on doing a S.A.S swap here in a couple of months and gathering a few parts. I was wondering which Ford 60 is the best choice for my truck in reference to spring perch width the 32" or the 36.5". I know that I could use either but which is the cleanest or best suited for my truck because of the shackles thnaks chris:smokin:

This has been covered before.

The 31.5" spring perch dimension works better. It more closely matches the frame width and the tires don't rub the springs as much at full lock.
