I'm about to begin the mustang 5x4.5 switch on my 95 tbird. Is it possible for me to get a rotor off a mustang, and set it againt my tbird rotor, mark the holes on my tbird rotor, and drill them myself? Or will this not be accurate enough? I would like to not have to buy new fronts rotors, and pay 75$ to get my rears redrilled.
