You'd be better off finding a 73+ A-body with discs for the swap. These parts will also be BBP.[/QUOTE said

I agree with - if you want to use stock 11.75" rotors (Cordoba) and `73 and up A-body knuckles, check out Mopar Action's article

This has the advantage of using easily sourced stock parts and 4 1/2" bolt circle. Also, AR Engineering makes a kit to mount Wilwood calipers on those knuckles. Hot setup.
