Hope you find some good ones. If not there are alternatives though quite expensive. There is a process using spray metallization, not unlike the original "centrifuse" process, that can sputter-deposit a metallic layer with a coefficient of friction similar to the original cast iron. It of course then requires machining back to standard size.

I've read of this process being applied to plain steel brake drums such as were used in early years on cars with external contracting rear wheel brakes. Plain steel has a lousy coefficient of friction and this a way to enhance the braking power. I've read of this process being done in the UK and I think also in Australia; I'd expect someone here in the US does it as well. If I wanted to track down a source for such work I'd probably start with Brian Joseph (Classic & Exotic) and Steve Babinsky (Automotive Restorations).
