Vent window issue

I have been putting my GTS and GT doors back together and it seems the factory fit of the vent glass is off on my unmolested GTS and about the same on my GT. When you close the vent window the glass hits the seal near the top way before it hits near the bottom. You really need to press relatively hard to fully close the vent window. It is not a wonder the latches glued to the glass pop off from the strain. I believe the main culprit is the pinch bracket that the vent window pin slides into. There is no adjustment on this bracket and it determines the angle of the glass. You may be able to bend it but I am going to drill out the pinch bracket on a spare vent frame and see if I can improve the situation and make it adjustable so the vent window fits more comfortably.
