Rear ends - explaination

Yes, you could use all of the brake parts. You will have to buy the e-brake cables for an a-body. The e-body rear will have to be shortened to a-body specs and the spring perch's welded on again in the a-body position. I would reccomend new axels that are a-body size but with e-body flange ends to work with the brake parts that came on the rear. I used Yukon axels but there are others. Moser and Strange come to mind. Keep asking questions and read all you can on these rears. It is not rocket science.
