Ron, you are correct, the break in the shape line is hard to notice, particularly at the wrong angle. These windshields have a very complicated shape. I had no success rebuilding the kit hardtop windshield frame as you did. The frame has so many compound curves that I built it in two pieces. I would have liked a smoother V in the center, but that is how it turned out
I first noticed this weird windshield angle while watching Twin Peaks. Thanks for reminding me that I should model the car in this show.Twin Peaks is a great show, and the guy driving this blue Caprice convertible is the lunatic murderer. These are imdb.com photos
Here is another GM convertible windshield but it's a Pontiac. Some cruise night shot.
