Alright I know I ask way to many questions but standing around the coffee pot this morning the question was thrown out there::

Is there a simple Rotor and bearing swap on a 72 swinger with disc breaks to go to the large bolt pattern?? Currently the guy uses the small bolt pattern rotors and had them drilled to 4.5.

Just asking, now for the information Highway to open up.

Not that I know of. Some folks try using Mustang rotors on there and I guess it kind of works but I've never tried it myself.

Is the only difficulty with this swap the inner wheel bearing difference between the rotors? If so, what about the Scarebird bearing adapters to put later rotors on a 70/71 B or E body?
