I have a set of 4 piston calipers which have never been on a car. I got them with my 57 Corvette gasser project that I'm puting . I have searched the HAMB and spoke to most of the contacts mentioned and got lots of info. But, I still would like to find someone who can rebuild them for me. They probably just need the piston kits as the pads are new. I am attaching a few pictures. Thanks, Bruce B.
