Long Time Listner..First Time Caller withWinshield Gasket Dilemma

On older cars I have seen two styles of gaskets
1) with a separate locking strip that is installed after the glass is sitting on the gasket,Then the lock-strip in inserted into a channel around the perimeter, to squeeze the folding lip onto the glass, and seal it
2) in the second type, the locking lip is part of the gasket, and it has to be folded in with a tool and lubricant.

IIRC,my 67 Barracuda had the first style. and my 68/69 had the second style. My 73 Dart also had the second style. After 73 I cannot say, but I imagine that the divorced strip was last used in 67.
