Just purchased some rear wheel weights for '60&quot; and looked specifically for older weights.  I came up with casting number H-1235 B in raised letters on some.  (Which according to parts book is correct for &quot;60&quot;)  H A 1235 B on another set with raised letters and H A 1235 B with raised letters inside a protective oval.  Can anyone confirm that the way I have them listed is more than likely the sequence from oldest to newest at least in that casting number?  Any other variations?  And any idea what in general years they would have been cast for each?
They fit right on through fleetline up to three digit as far as I know.  Thanks.
