Rear window and seal install.

[Slow Build]

I've looked at a few of the threads on installing the rear window, but I have a few questions.

1. The Factory Assembly Manual shows the two ends of the weatherseal meeting at top center and says use cement weatherstrip. Nobody has mentioned using adhesives to connect ends. Does that sound right?

2. How do I put in the weatherstrip retainer? I'm guessing soap and water, but any tricks to this part? Do you have the two ends also meet at top center? I would think this needs to be done before puting window in the cab.

3. What is the best way to cut the extra seal off? I don't want a gap up top so I want to make sure I that this weatherstrip will shrink after install.

Any info would be appreciated.
