Crap, totally forgot to add that..thanks.im assuming any bbp backing/drum plates will work.

If their backing plates off an A-body that's probably true. All other body styles had a different offset and will only work with axles of that offset. And axles are different for all rearends, 7-1/4, 8-1/4, or 8-3/4.
