It all depends on what engine you got. It may not be worth it to get a smaller rear end, a smaller rear end cannot support the power of a V8. But if you have an I6, you should be ok. Also you would need to find an 8.8 or 9 in in order to handle the power and torque of a V8. In fact I would suggest going to the local Junk Yard and checking around for a ford 9". It would probly be cheaper too.
9" with 3.55 Open
Global West Coil Over Suspension
4 Wheel Disc Brakes
200 -> 289
JBA Shortie Headers
Flowmaster Super 44's
17" '04 Black Bullit Rims
18" Deep Dish Rear
I don't know the bolt patterns, but I believe the 7.5" has a different bolt pattern than the 8 inch. Master Power Brakes has some good kits. Not too many Ford cars came with discs that used the 8 inch or small-bearing 9 inch.
My bad on the misunderstanding I have a V8. I don't want to switch out the rear end I just want to use the brake set up from the 7.5. I was just wondering if I could remove the brakes from the 7.5 and put them on my 8". Oh by the way bolt pattern is the same 5- 4.5
