I am in the market for a new 8 3/4. I have an 8 1/4 now with 10 x 2.5 drums and I was wondering if I could use those on a new rear end.
That's what I did with mine, 20 some years ago. Of course I'm assuming you're talking about a bbp 8 3/4.
Axles will not work. Backing plates will be a major hassel to get to work. Just buy the correct stuff.
What Dave said. The 10” BBP brakes are all the same, 8.25 rear axle BBP brakes will bolt right on to an 8 3/4 as long as you’re using BBP axles in the 8 3/4. For that matter the BBP brakes can be exchanged from 7.25’s, 8.25’s, 8 3/4’s, and Dana 60’s. It’s only the SBP stuff that doesn’t interchange between axles.
