I PUT A ONE PIECE WINDSHIELD IN A 1946 CHEV. PANEL TRUCK (SAME AS P.U.), THE GLASS IS GLUED DOWN TO THE PINCH WELD WITH URATHANE SAME AS A LATE MODEL WOULD BE. I DIDN'T REALIZE BEFORE I GLUED IT IN THAT THE GLASS WAS SLIGHTLY TO BIG AND IN A FEW PLACES THE EDGE OF THE GLASS IS TO CLOSE TO THE PINCH WELD TO ALLOW FOR A RUBBER TYPE PINCH WELD MOLDING SUCH AS A T MOLDING. ANY SUGGESTIONS ON HOW TO TRIM IT OUT WITHOUT REMOVING IT?
