10x2.25 rear brakes

None.

I’m sure what you have are actually 10x2.5” brakes. And pretty much everything came with the 10x2.5’s, most of the RWD cars from the mid sixties on all the way up to the late eighties, everything that was 5x4.5” and didn’t have 11” drums. Most of the half ton trucks and vans too.
Well my shoes are (2.25)
