What is the rope method when installing a windshield on a 79 Ford f150?

I'm trying to do the job myself. According to the forums I've read it's pretty simple. But Most of them say they used a small rope to put it back in place. Where does it exactly go? And do you start pulling it off from the inside of the cab or outside?

I have done many. For a first timer, you will need help. Just someone to apply MILD pressure on the outside. Here is a good video of a rear glass, front is done the same way:

If yours has chrome trim, that is installed before you install the glass.

Think of the rubber sal like a capital H. Fit it round the glass. Fit the rope round the outside groove of the H. Hold it against the frame. Pull the rope inside to flip the edge of the seal over the metal. It's pretty easy. Then go round with silicone seal.

If the rubber seal around the windshield has a "U" shaped edge you wrap the rope around the complete window in that you channel and over lap it about 6". Then you place the windshiel on the body opening and while another person lightly holds it in place you get on the inside and carefully pull the rope to make the U channel inner lip flip over the opening lip. If the windshield is held down with ytoo much pressure you may rip the rubber U channel and then you need a new one. Silicon spraying the rubber helps make the rubber flip over the body opening lip a lot easier.
