Yeah, I just spent about an hour at Autozone with my brother pouring over brake parts
Lincoln Mark VII rotors will bolt up (same bearing sizes as the GT mustang with a 5 on 4-1/2 bolt circle and 11" rotor diameter) They are part number 5463 (Autozone) and are the ABS rotors. However the hub for the wheel is about a 1/4" bigger in dia than the Mustang's and possibly needs to be machined down as I'm almost certain that Ford's wheels like most manufacturer's are hub centric (meaning the hub is used to locate the wheel rather than the lugs)
The rotors are about 80.00 bucks each, which isn't to bad I guess, I'm gonna get them payday and check things out. If they fit I'll take them to get the hub machined down and possibly cross-drilled (for that sexy look
)
