On the top front facing portion of the windshield hinge there is a lone torx screw. On both sides of my TJ's windshield the screw has nothing useful to screw into and keeps popping out, revealing the rust hole behind it. (see pic) I'm concerned about more water getting in, where it might go, or sit, and the damage it will do. Is there a way to repair/replace whatever it is supposed to look like in there without replacing the entire windshield frame?
