Are you swapping complete rear ends or do you wish to put discs on the drum rear? What years are involved?

Here's primer that should answer many of your questions:

If you're putting an 82-88 rear in a 90+ car the combination valve from the 82-88 won't fit. The tube nut threads are different. Check the 10-Bolt FAQ sticky for brake info.
