windshield replacement

[antilley]

75 Pickup and I need to replace the windshield. The old windshield is out and the opening has been cleaned up ready to go.

I am confused on which rubber to order .... I see some on ebay that seem to be one piece .....suggesting you would put the rubber on the window -> Insert the window and use the rope method on the inside .... with this method do you use adhesive? is this an easier way to do it than some of the other things I have seen that have a locking strip.

Thanks in advance.
