Best source for rebuilt calipers?
 

I need to replace the rear calipers on my 81 SC. All the regular auto part web sites list different ones ranging in price from about $35 to about $70. Some of them are rebuilt by A. Cardone. Some by Nu GEON, and a few others. Some say OE piston. Some don't. Am I safe buying any of these calipers? Any BTDT?

I have used Raybestos rebuilt Ate calipers for Mercedes ... they looked and performed as new at a much lower price! No info on who rebuilds them for Raybestos. They are available from many sources.
