I assume that you have done a 31 spline conversion on that 8.8? What year model did the 8.8 come out of. My buddy took disc's off of a Turbo Coupe rear end and put on his 8.8 rear end. But it was an 86 model 8.8 might not matter but it might... I dont know.

His works fine

which 7.5 rear end did the brakes come off of .
if its from your car yes they need the proper axle ends to fit the rotor on everthing else is the same . check the spline count cause 8.8 have 28 stock and then you could use tw0 areostaar axles i cant remember right of which side is the same driver or passenger but you need two of one the areostar diff is a little ofset. do a search if you have a 28 diff. one side of the ranf\gers work also.

From my understanding of the subject, the 7.5 rear end (94 and newer) discs, caliper mounts, calipers, and axles will slide right into a formerly 4 lug 8.8 rear end (assuming all is stock) they both have 28 spline axles (stock) and the axles are the same length as the t-bird t.coupe axles. (3/4 of an inch longer an axle than stock 4 bolt mustang axles)

I would just like to mention that I have never counted the splines on a 94 and up 7.5 rear I have just been told they are 28 spline.

8.8 rear in question is a 90 rear..rear brakes in question are from a 95 7.5"...i am not worries aout the axels becasue they will be 31 spline like the rest of the rear
