As far as the first picture goes.....the center bar is held to the frame by 3 (I believe) screws. It's possible that one or more of these screws has backed out, broken off or fell off. Unfortunately, you need to remove the headliner to get at them (not an easy job on a T-Top car.
I know I need p seals, and I, check the screws, at the center bar, and have even flip the bar around. the first pic I tried not to show the missing p seal. I was trying to show how the glass fits into the bar. At the back of it is tight, in the front of it has a gap I don't know how to explain this part but. when I push down on the glass it feels like I'm prying against the glass get to latch.
