Front and rear windshield pinch weld

I don't quite understand the question but,
If you are trying to delete the rubber gasket around the glass.. it cant be done.
The rubber gasket has a H profile. The center web of that is approx. 1/8 thick.
That requires the OEM glass to measure at least 1/8 inch smaller than the fence that the gasket sits on. The OEM glass is actually more like a 1/4 inch smaller than the fence so it will go together without the fence cutting the center web.
