Having a heck of a time finding a rubber windshield gasket for an 1985 G2500 Vandura. Basically I want to do a non-glue in replacement of a cracked windshield and I hear the rubber gaskets leak less than the urethane-glued approach.

I have searched ebay, amazon....you name it. I can find the pick-up rubber gaskets no problem but striking out with the van. Please let me know if you know the part number or a company that sells them.
