Jerry,
Crown races aren't very standardized but there is some
interchangeability. An NR race probably won't work
with a Tange Levin HS and vice versa as Levins use
5/32" balls and NR/SR headsets use 3/16". Bearing
size that the part is designed for is one of the
considerations, the other is outside diameter of the
widest part. You'd want clearance enough to not drag
inside the lower pressed cup but not so much room that
dirt would have an easy entry. There are probably
some NOS Campagnolo crown races in circulation; if you
want to pay way too much for one your LBS might get
one from Euro-Asia Imports.
