72 Duster Rear End and Brakes

[Vroom72]

I have recently rebuilt my 318 duster and on the dyno I am creating 423hp(at the crank) and I am curious where everyone has bought their 8 3/4 rear ends??. Also I was wondering if anyone has done a disc brake converstion with their 8 3/4 rear ends. Im looking for info on a 4 wheel disc conversion kit. Thanks in advance!!! :notworth:

I have a 68 B-body 8 3/4 rear axle in mine and we just put a 65 B-body 8 3/4 in my friend's 71 Demon this summer. Just need to move the spring pads. You get the large 5x4.5 bolt circle with factory parts.

For the disk brake kit, DoctorDiff has two sizes.

Great kit because it has well designed calipers, not the crappy GM eldorado ones from the 70s. Also you can keep the stock wheel bearings.
