Switching to BBP

I am switching to BBP on the rear of my 68 Dart. I have small BBP drums on a 8.75" rear end from a 72 Duster on it. I have 10 x 2.5 BBP backing plates with struts, levers, and other hardware. What I need are drums, shoes, and cylinders. What year parts do I order if I get them from Advance, Autozone, or Summit? Thanks FABO.
