Using mustang rotors for 4.5" bc

So if we have the K-H brakes we should be able to get 4.5" BP for about $200. Depending on your machine shop prices. That sounds great to me. Sign me up.
Oh wait, my son works at a machine shop. Thanks for all the hard leg work Longgone.
Next question though. What about the stud difference ( 1/2 on front 7/16? rear) Can I just have my rear drums and axles re-drilled for 1/2 studs?
