Yea, it sounds like you need to bring the crank in and
have it ground to the right size on the thrust bearing
area.  I wouldn't sand the bearing down because like
you say, you'll remove the other coating, plus you'll
be driving around this car with a home brew crank
bearing.  Not something that sits well in my mind.
