12” gm rotors

I believe I read that the early SP cars used redrilled 12” gm 1978-1990 full size front brake rotors which I am interested in,if they fit Mustang ll. Does anyone have an source for these?

Rockauto lists the rotors - I just checked and they have 12" rotor and hub assemblies from both Raybestos and Bendix.

That looks to easy, have any idea what it would cost to have them redrilled? I have Mustang ll Will the off set be close? What bearings would work? Thanks for your time.
