rear question

Smirnoff · May 7th, 2008, 03:53 AM

i just bought an 82 mustang gt i was just wondering if anoyone knew what rear came in them because the diff looks really small and it likes to spin one wheel so i dont think it is an 8.8 sadly i think it is a 7.5

if its orig its a 7.5 ...8.8 came out in latter 85 and 86... i had a 7.5 with 345 gears held up nice,but usually wont to a huge amount of power..

hahaha 7.5s don't hold any power...... that will probably be the first thing that breaks.

i got a 7.5 in my 83 lx and ive heard the most common things that go wrong with them is the axel tubes bend. and thats no good. im switching to an 8.8 out of my 86 gt parts car

I broke mine powershifting into second with my stock 85 GT. It sheared all the teeth off of the pinion, 14 teeth off of the ring, busted the carrier and broke both main caps.
