This guy is selling his rear end with 3.73s, an eaton locker, and 31 spline axles. my question is will it fit my 2001 mustang?
Thats why wheel manufacturers offer different back spacings, so you can do just what you are saying.Its a 11/16" shorter on each side. You cant run a bigger tire but you can "tuck" your slicks in for a better look visually. I like the 94-98 GT live axles over any other 8.8.
