This method is simple, easy and efficient as well as cheap. You can use old brake springs to make steel wire rope inserters. Windshield removal is tough work, especially getting a good one from the junkyard. I have removed several windshields without damage. You may replace the windshield using less than $50 for the entire job if the windshield is from a junkyard.

Note that when removing the urethane at the four corners of the windshield, if pulling isn't effective, you can use a sawing motion instead. When pulling the rope, if there is uncomfortable resistance, please check and see if it is caught on any part of the metal frame, such as the VIN tag.
