A Body LARGE bolt pattern rear brakes

My so-called brain isn't functioning very well right now, and try though I might, I still am not 100-percent sure about this: After I put 4.5"-bolt circle axles in my 8.75" A-body housing, is there any reason why I can't use a pair of '73-up drums off a Duster with an 8.25" housing?

I don't want to go to the trouble of putting the whole B-Body hardware system (backing plates, shoes, etc.) on my car if an A-Body drum from a 1973-up 4.5" bolt circle, 8.25" rear end willl work.

I'm pretty sure from what folks wrote that it will.... just want to be certain.

Thanks for any info!!!
