Chuck,
I think I see the problem. picture 3's arrow points to the start of a bevel that the edge of the windshield frame is supposed to fit into. It is ok at the bottom, but about 1/2 way up (picture 1), it looks like it is not locked in.(it's hard to tell from the picture) See if you can get it to lock in all the way up. then the top part should rotate into position.
Let me know what you find.
