I used to go to big Corvette shows and there were vendors that bought cores and rebuilt them. Vette Brakes and Products is out of business now. Lonestar calipers might. Maybe Muskegon Brakes? That one is really not all that special, GM disc/drum is used in a bunch of cars and trucks for years. But I know what you mean. The one on my '83 K20 is stuck and I bought an aftermarket one but I can't quite bring myself to install it yet.
