60-63 Chevy/GMC Windshield Gasket With Trim Groove. This windshield gasket is used with 60-63 Chevy trucks that do have a factory chrome trim around the glass. Windshield is easily installed by putting the seal on the glass first, then using the "rope-in method" starting at the bottom and working to the top pulling the rope from inside the cab. Gasket is constructed from ozone resistant EPDM and made to original OE specs. Limited Lifetime Manufacture Warranty.
