I bought a bracket from a company called Scarebird. They provided me with a steel bracket that bolted up to the drum spindle, I used a corvette rotor and a willwood caliper. this was for my Chevy II. the brakcet was @ 100 the rotors were @ 100 and the calipers I bought on ebay and rebuilt them @100.
They have other brackets available that use stock calipers here is the link
