Reply to "Vintage racing brakes"

Those T-bird calipers may not fit all Pantera wheels. Specifically, that raised ridge at the outside bottom holds the connecting passageway for fluid flow between caliper halves so it cannot be ground away, and it hits passenger car Campagnolo wheels unless a spacer is used. They work OK on some aftermarket wheels without spacers. And the one time I tried turning down the OD of a brake rotor to fit, I wound up using carbide lathe bits and slow speed- those suckers are TOUGH and the cuts are interrupted so your carbide tool chips!
