hey everybody! i'm new to this site looks great. i tried a search on here couldn't find info. on my subject. what parts would i need to put rear disc on 85 chevy pickup? i found some kits, they are a little pricey. i know this is cheaper in long run, but working on budget. i can go buy a part every once in awhile, till i get it all bought. i just need to know what rotors and calibers etc,etc, i need. thanks in advance.........nathan
