I found my stuff at the junk yard from a 69 Grand Prix. All I will end up using are the spindles as I just bought all the rest of the stuff from NPD just yesterday. I bought all new bearings, calipers, brake lines, pads etc. No matter what you do, it's not an inexpensive upgrade bt the time you round everything up. If I had not already had the spindles I would have bought the 4-wheel disc set up someone on this site has for sale and been done with it!
