Problems Identifying and Matching up new Brake Calipers

exactamundo. fire up the grinder with a 80 grit flap wheel and have at it.

or... if you have the room, i'd bet a slice of ham that a little 1/4" billet spacer might just take the wheel out enough to clear.

but the spinny wheel of death option is free and sparks are fun.
Gonna do some small depth cuts on the area that I know was rubbing.
Will do both calipers just in case.
I think my son's shop has a belt sander to smooth it down.
