Gimmie a Brake HELP

Homework,Homework,Homework, this was an original BBP setup but one of the backing plates was damaged, so not knowing the difference I purchased a set off a fellow FABO member cleaned them up all new hardware and presto there not the right ones!

So to making things totally clear/fuzzy with the right BBP A body backing plates should/will fit the original BBP drums I just spent hours on, or just start over and get the B body set??

All BBP backing plates for a given size are the same. All the 10" BBP brakes are 10x2.5", it doesn't matter if they were for an A-body, B-body, E-body, FMJ, whatever. They're all the same.

I'm not entirely sure what all of your current parts are, although it's clear you have some SBP brake parts in there. What you need to do is pull the backing plates you have and measure them using the process I outlined here, making sure that the "bumps" for the e-brake cables aren't holding the plate up. Converting rear drum brakes from SBP to BBP

Then you'll know for certain what plates you have. You already have BBP axles, so, there's no way you're going to make SBP brake components work. None. So you need to get a set of BBP brakes, and that means 10x2.5" drums, 10x2.5" shoes, and backing plates with the correct offset. The hardware you can re-use, but that's it (brake spreader bars, springs, e-brake levers and hardware, etc).
