Our car is a 85GT that is about #3150 w/driver and has a faceplated TKO600 and a 550HP? 363. (hoping to run mid-high 10's) We were going to run 4.30's with a Detroit locker in a 8.8 and was going to use Moser 31 spline axles. Are the 31 spline Moser axles plenty strong enough for our combo? At what point do you need to go to 33 or 35 spline? Thanks!
