I have not been able to find anybody listing these for B body cars. Rock Auto ... nobody. Not saying they did or didn’t come with them.... just that they don’t list it as an option.
You know after checking my notes on the cars I pulled those 8 3/4's with 11x2" brakes from I see that they were C-bodies. Still mid-sixties C-bodies, but C-bodies none the less. They should list for more than just '72's but those parts lists aren't always 100%. They should be fine, the Imperials were the only ones that came with a different bolt pattern and I think that was late fifties/early sixties anyway.
