Urgent!!!!

Don't have a diagram but it would be preferred to have the windshield out for the liner install. It's the windshield gasket that is in the way. Under the gasket on the top, the frame is punched out in "V" shapes so the headliner has something to grab onto after stretching it. You could somehow, position the gasket away from the the top frame to access that area. It's a whole lot easier w/the shield/gasket removed.

BTW, the rear glass/gasket is verbatum.
