I spoke to a windshield rep and he said, depending on the type of gasket, the top is usually sealed from side to side. The sides and bottom should be a tight friction fit. Also, there should be a small gap between the ends of the gasket where they meet in the bottom center of the windshield. This acts as a weep hole. If the ends meet anywhere but the bottom its installed incorrectly. I've since sealed the crack with windshield sealer until I can speak with Thor. It looks like it sealed up nicely. I haven't attempted the headliner clips yet.
