Help needed installing front and rear glass.

I had to do one back when i was in school, back window of a older chevy pickup. anyways What we did was take rope(obviously smaller rope) run it in the channel of the gasket, stick a corner in and just pull on the rope to make the edge go around the pinchweld, using soapy water in a bottle helps too.

hopefully this helps and you get an idea of how its done, If your still not sure i would probably just call a glass guy they will come to your place and do it, and for what you would pay vs buying new glass if you break it, it would be cheaper.

Just a though


Good luck:-D
