B Body drums on an A Body

Looking to convert a 68 Dart to BBP. Maybe discs on front, as I do have a set of 73 BBP discs and a booster from a 70 Fury, but question is this: are BBP A Body drums and BBP B Body drums gonna fit the same? BBP A Bodies look scarce, so since BBP is BBP, is there anything that's going to keep me from using B body drums? Will either be using C-Body 8 3/4 made to fit, or will find an A Body 8 3/4 with 15x7 steels.
