The calipers are fairly easy to rebuild if the bores are good. Whichever vendor you choose, be sure to communicate all expectations in advance and keep a record of your agreement - i.e. no swap outs, grind-out of casting #s or stampings, no restamping, whether you want calipers stainless sleeved, etc. If the booster is pitted you could lose some stamping detail during the process. I'd talk to Jerry first, just be patient in reaching him.
