Rear ends

If I had to throw one out there without any information in regards to the OP is doing with the car (lol) it would be to locate a 8 1/4. LBP, will bolt right in, and are a good all around choice. I beat the brakes off mine back in the day and never broke it. I probably never saw anything less than a 1.70 60ft. so it stayed in the safe zone.

Past that it boils down to needs, wants, and your skills along with your wallet....
