8 3/4 rear brake swap - cuda

Help please, I own 70 GRAND COUPE with a 9 bolt small rear from factory in it.I want to put a 8 3/4 unit in it,and have a 8 3/4 rear housing,backing plate only ( no brake parts)I was wondering if all the brake parts interchange.The backing plate looks the same,just want to hopefully use all the other stuff off it.Thanks

You can look at it, but I don't think they are interchangeable. When I built mine I purchased all of the brake assembly at NAPA.
