Problems Identifying and Matching up new Brake Calipers

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.
just.use.a.grinder.

you don't even need to take the caliper off.

buzz it a little, test fit. buzz it some more, test fit. buzz it again, voila it fits! next!
