SBP 8 3/4 backing plates, drums, guts

Well, kinda. I stopped at O'reilly's, they have 10" SBP drums, but she's telling me they use either 2 1/4 or 2 1'2 shoe's, can't remember which, 56 bucks each, one day wait.

I would be shocked if they had anything small bolt at all, and if they use anything other than 1 3/4” shoes, they are not small bolt and not correct for A body 8 3/4” rears. I would venture a guess that they are large bolt for 73 and later 7 1/4” large bolt axles.
