I have a 1980 el camino and I wanted to do a disc conversion on the back. For the front I am planning on doing Wilwood dual piston calipers but otherwise keeping that setup the same. I don't really know what kind of calipers I'll need in the back so I was looking for suggestions on some conversion kits you guys have seen. I also want to replace the booster/master cylinder and I want to keep the parking brake.
