Recently I was under the dash re-doing wiring and looked up to the underside of the dash where the Center rod comes through from the top. The rod was quite lose which I hadn't noticed from the top of the dash along with the windshield. It was being held in place loosely with a couple of larger nuts used as spacers with a proper nut on the end. I could push up carefully on the windshield and the bottom edge of the glass came off the bottom trim exposing loose vinyl which as previously stated had bubbled. I decided to make a proper bracket to spread the load of a tightened Center windshield rod and decided to repair the bubbled vinyl at the same time. Building on the advice previous given above, I applied 3M Super 90 and glued the vinyl back down and tighten the Center rod with my newly fabricated support bracket depicted. The 2 small bolts coming through the dash are replacing 2 screws which are holding the male part of the dome fasteners on top the dash for the tonneau cover. The windshield is now solidly held. I will secure it further with lock washers.
