Title: rear end gurus please help
Post by: shame302 on November 16, 2004, 05:31:58 PM
how much shorter is the rear diff in a fox mustang? ive got one i can use but if i cant im tossing it. would there be any problems with puting my tbird axles in the mustangs housing to make up the length? or would that be a bad idea? :dunno:

The Mustang axle assembly will bolt in. The quad shock mounts are in a different location than how they would be mounted on a TC 8.8. Simply swap your axles in and you should be fine.

awsome..thanks. i wasnt sure if that would work. i was going to yank the 7" out and use the trac lok in my rangers rear for a little better traction with that and stick the mustangs axle assembly with the 7" rears axles in the tbird temporarily. the turbo coupe rear i have isnt rebuilt yet. anyway...thanks again guys

You might need offset brake drums for the shorter housing.  T-birds with short (Mustang-length) housings from the factory (thru mid '85, I believe) used different axle shafts from the later ones with the long housings.  The wheel bearings will ride on a different portion of the axle shafts, so be sure yours are machined that far inward.  Mine weren't ('88 Bird using '85 TC housing).

i think ill just end up tossing the stangs axle...ill stick with my 7.5 till its toast or the turbo coupe rear diff is finally rebuilt....figure ill just do it the right way. i just figured it would be a way to have a 8.8 without hasseling a swap to disks yet....
