65 glass install

Gasket on the window pulled in with rope is the only way I've ever done it. Done literally hundreds. It's easy. Once the gasket is on the window and the rope in place I squirt some Dawn dishwashing liquid all the way around on the rope, place it against the pinch weld. Literally ten minutes later, the window is in and you can put the lock strip in. I always rinse the Dawn out with cold water, let it sit a day or four to dry completely then run a bead of heavy duty silicone calk between the outside of the gasket and pinch weld. I have never had one leak doing it this way.
Thanks for the good description of your method.
I have a gasket on order from DMT, as well as a new windshield from a glass distributor, that search came from your recommendation Rusty, thanks again!
I've installed plenty of rear window sliders on pickups, always placing the gasket on the frame, and roping the glass in.
So today I pulled the old shield & gasket out, pretty easy.
After reading your method, and seeing the difference in thickness of the fence gasket lip vs the glass gasket lip it makes a lot of sense to follow your method. The fence gasket should certainly be more flexible than the glass side.
A few questions:
Do you install the lock strip after roping the windshield in or before?
Just regular black silicon instead of window sealer?
My old, I think original, gasket had a very light coating of gray pliable putty like material spread thinly on the fence, a bit heavier concentration in the corners. Looks like what we called dum-dum used for installing aftermarket van windows & sunroofs. I guess that's what to factory used back then.
