disc break adaptability

F-Bodies (Aspen, Volare, etc.) never came with 11.75" brakes. Only the B-Bodies.

Not impossible to find them on the car, but they weren't factory. Don't think the cop cars even came with them. Pretty sure my 78 Super Coupe didn't.

Doesn't mean the rotors and adapters are worthless, just that they probably wont be the big ones. Calipers are the same regardless of the size.
