1975 Dart Sport Windshield Trim
Slappy, after looking at the pic again it is the seal that needs some tweaking. Look at the lines on either side of the curve at the top of the window and how the seal and trim line up. Just at the curve is the trim and seal taking a different course. Looks like the trim has to come off and and perhaps take a small to medium plastic putty knife and round the spreading edge and corners and just push the corner along the edge of the window until you get the desired countour.
