I'll add one thing- if he uses the Mustang rotors to convert to the large bolt pattern on the K-H brakes, rotor and hub availability is no longer a factor; they are commonly available. Plus, you rid yourself of the Mopar's 2 piece hub and rotor and get a 1 piece unicast hub and rotor- no more pressing wheel studs in/out to change rotors and dealing with swedging.
