Disc Brake swap-A body Rotors

There are small bolt disc setups out there I know a couple of guy's that are running them. As for finding parts not sure how hard. When I was looking at the disc brake up grad on my car, the front calipers were Kellsy-Hayes two piston with the mopar small bolt setup and were about $300 to replace. The big bolt calipers are about $30, though they are single piston.

I think that both Moser and Strange make an A-body 8 3/4 big bolt axel and there may be others out there as well.
