Are all Duster windshield gaskets the same ?

What I was wondering was .....
Is it possible that one design was used in the early models, then somewhere along the line it was redesigned and the later design became the standard.
This has happened with parts before. The new design becomes what all replacement parts are patterned after. Maybe the revised design works in all models but is not factory correct for the early ones?
If that is how it is, that is fine. This car is not an OEM restoration anyway.
