Most believe (myself included until recently) given Superior's parts frugality that the same glass was used for multi-year runs. '57-'58 Superior triangular corner glass is different than '59-'60 (will eventually get around to posting pic proof). Likewise, '61-'62 trapezoidal corner glass is different than '63-'64*.
'63-'64 above; '61-'62 below.
They're similarly shaped, as '57-'58 and '59-'60 are. Until out of coach and placed side by side however, the differences are not as readily noticeable. Below '63-'64 is placed directly on top of '61-'62.
Straight line measurements @ widest points, not taking curvatures into account:
'61-'62 = 17.5" x 13.5"
'63-'64 = 17" x 10.5"
*'61-'62 Superior Cadillac corner glass carried over and was used on all '61-'64 Superior Pontiac. '63-'64 Superior Cadillac glass was not utilized on '63-'63 Superior Pontiac.
