Dodge Dart 68 windshield rubber, HELP!

It may be an optical illusion but I would measure the window opening (top to bottom) and the glass to be sure the two are correct for each other. the glass in your photos looks not as tall as the window opening in your dart. (disregarding the incorrect rubber seal in the photo)

Obviously if you took the glass out and it fit correctly to begin with you can disregard my suggestion


(good looking Dart by the way)
