Windshield gasket?

Mike, I got one for my 73 duster from year one, but that was before I knew better.
I kinda like laysons (pretty good prices)

Part # Description Price Qty.
PR-WCR914 All Dodge Trucks (including Little Red Express) front windshield weatherstrip.
72-93 Dodge Truck $70.00

As for the thickness thing, I think the lock strip will mash the gasket enough to touch the glass
