7 1/4 big bolt pattern and 8 1/4 bbp the drums and brake hardware all interchange right? Both ate 11" backing plates and look identical.
Just double checking...

Yes. I've done the complete brake swap from a 1973 8 1/4 BBP to an A body 8 3/4 and from a 1974 BBP 7 1/4 to a B-Body 8 3/4. They all interchange as long as the axle housing flange bolt spacing is the same. Just make sure you keep the backing plates and drums from the same size brakes.
