I can't confirm your question... Can you redrill those camaro rotor/ hub assemblies out to a 6 on 5 1/2 circle? I understand your question and your intentions as I am trying to do the same on my 1940 gmc. Buffulo enterprises is a good place to call for this question. He has made brackets for both.
I would ask the guys at NAPA if you could borrow their brake book, and see if you could find a 6 lug rotor that has the same diameter and thickness as the one used in the 5 lug kit. Then hope, pray, wish, or bet the offset in the hat would match that of a 5 lug set-up when everything is bolted in.
Good luck!
