Maybe I'm having a blonde moment and am confused. You're asking about trim, another is talking about gaskets. "Correct" gaskets to the 67 Barracuda are unique to that year only. The gasket has a lock strip that locks the gasket around the glass. The lock strip I've seen on a 67 Cuda convertible was chrome plastic. The only trim I recall was on the A-pilar and the windshield header.
The notchbacks I have seen have the black rubber gasket and a lock strip. The outer part of the gasket and the lock strip are covered by stainless steel trim.
One of the things I have seen is about windshields on A-body MoPars is that they are not all the same height. If you have a 74 Valiant, the windshield is taller than the one on your 67 Cuda notch back.
