Hi all. I am posting here in the hunt for the two round dash vents/louvers that were fitted to 1961 and possibly 1962 catalinas and bonnevilles ( possibly parisiennes also). They are the round ball type with an outer housing that shapes to the dash. See pictures inserted below. I am from Australia but hoping someone could take the time to help me out.
Thanks Jason.
