'75 duster windshield gasket
I have a vinyl top '73 Duster in my back yard from which I just pulled the stainless trim last week. Aaron drives a non-vinyl top '74 Dart Sport that we replaced the gaskets on a few years ago. And we used/parted out a vinyl top '76 Duster back when we rebuilt his Dart Sport. As best I can tell (and recall), they were all identical with regard to the window gaskets. They all used the round locking strip, the reveal clips were all the same, and the stainless trim fit exactly the same (I used the same tool in the same manner to remove the trim).
I love mysteries,
Jerry
p.s. A few photos would speak volumes in this case.
