i have been digging through this for a couple of weeks. cost runs from $400 for smaller s-10 type calipers tO $550 TO $675 for oe style cast calipers or simular after market system. to the $1000 and up performance set up. i found a company that has a kit that was made by ssbm, but sold under another name. they were my front runner. i have there info if you would like. i'm decided to go with a donor system.
