swapping my rear end

checkers69 · 11-29-2009, 07:36 PM

Hi I am a new member here. I just have a question about swapping my diff. I have a 1994 mustang with a 7.5" diff. I bought a 8.8" diff out of a 87 turbo coupe. Now I went to put the diff in and noticed my 5 bolt axles out of my car were longer than the axles in the turbo coupe thus not sealing properly and not being able to bolt my brakes on. I was wondering were I can get 5 bolt axles the same length as the 87 turbo coupe so that my brakes can fit. I hope someone has a solution otherwise I have to sell my freshly painted diff with new bushing's and seals. Greatlly appreciated.

p.s somone told me axles from a 94-98 will fit in this diff but they didn't specify if they had to be out of an 8.8 or 7.5 diff. I know mine don't fit so I hope ones out of an 8.8 will.

The rear end was widened with the new body style in '94. I think you'll have to find a new rear, unfortunately.
