AMC 20 Disc Brake Conversion Parts List

So,

Been reading through posts getting ready to do a one piece axle upgrade with a rear drum to disc conversion. I think I have the general steps/parts down, but want to make sure I have/get the right parts, and know the right place to get them. I have a 78 CJ with Front Discs.

If I am missing something, let me know

I put the parts I have the most questions about first. To All Readers, Still researching, so use this post with Caution!!

If you are looking for a how to try these-There are lots, but these are pretty good

I purchased a 79 CJ7 a few months back and it already had a disc brake conversion on it. The original owner used this system. It might help you with your parts list. The rear brakes are from an Cadillac El Dorado I believe
