I think the Vented vs Non Vented is an emission thing, right?  I'm not an expert on 72's, but it's going to come down to if you have the emission (N95 in 1970) on your tank or not.  If someone has replaced the tank you'll just need to know if the emission vent stuff is on it or not?     Right?

@scf100  this is the 1972 parts book.  Looks like it's either locking (with or without 3 keys) and non locking.  Doesn't seem to be any choice between vented and non vented.

Vented was only 70 , 71 up used other ways to vent due to emissions
