Differential Compatibility
I am currently restoring a 77 stepside with a 400 (not cc) engine, 3 speed hurst shifter. I was wondering if anybody could tell me what would be the best differential from a scrapyard which would be compatible with this. Also, which gear ratio would be best suited.

Without knowing all the details, I suggest the following:
1. Ford 9" rear axle with 3.50 or 3.73 gears (31 spline at a minimum)
The reason for picking this diff, is simple. It really is a strong rear-end and also easy to work on. Try and find one with a limited-slip or locking rear.
Good luck with your rebuild.
