Duster Windshield Install

Your description is the way I've done it dozens of times. Use a small nylon rope in the gasket groove to peel the lip out into place. Wrap it completely around the glass and overlap it a few inches at the bottom. Lube the rubber with some liquid soap or gritless hand cleaner Set the glass in place at the bottom with the ends of the rope inside the car. Slowly and carefully pull the rope ends and as the rubber lip slides into place, gently push and tap the glass with a flat hand (no ring!) Don't try to force it or pry with a screwdriver. If you take your time, you should be able to get it done.
I agree with others though.....if you've never done one, you'll probably break the first few until you get the hang off it. If you want to learn, go to your local pull-your-own parts place and practice first. Start with a flat back glass in a pickup. They're about the easiest to do. Then try a fairly flat windshield....the wrap around ones are the toughest. Good luck!
