Problems Identifying and Matching up new Brake Calipers

So what's the beef? The 73 and up A body brakes are arguably among the best. Just clearance the calipers and rock on. 15 minutes work with a die grinder. They aren't hitting all that much.
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.
