The trick is lots of the foaming glass cleaner. It lubes the rubber and makes it slide much easier. I watched the guys put the 2 piece windshield in my 49 Dodge truck the other day. Those don't have the lock strip. You put the glass in the rubber, put a 3/16" thick multi strand cord into the slot that fits onto the pinch weld with the cord crossing each other at the center. One guy is inside pushing the glass and the other guy is outside pulling the cords a little at a time. Lots of foaming glass cleaner, and it slid right into place. It only took them about 30 minutes to install the windshield, and most of that was putting the glass in the rubber. It was pretty cool to watch.

A year or two ago a buddy and me tried to install a glass using a string, we got 6" into it and the string broke. Lessons learned? The string isn't string but a small diameter rope, and we didn't have anywhere enough lube on the rubber/glass (and we were using water rather then the foaming glass cleaner). Gene
