I did allot of research on this in attempts to avoid buying a 6 lug kit. I don't know exactly what rotors to use, but have some ideas. Hoses, calipers & brackets per above work for 5 or 6 lug. '70-'78 or so Camaro calipers are what's in the kits. In the end, I'll probably buy a kit. Are you are going to go 6 lug or 5?
Ebay is a good place to see trucks of various colors. Other sites that sell trucks too. There is also the Stovebolt Gallery.
