So I have this 168.005 connie that I want to get a new crown for, but I’m stumped as to which one would be a correct fit between ref 4219 and ref 4204. I noticed that the connies from the 60s are much more smaller than the connies from the 50s, so would that mean ref 4204 be the correct crown?

help is appreciated!
