Found this, maybe it will be helpful as it states common ways windshields are installed.
Other than mounting quarter glass with screws (such as in the Honda Civics and Accords), there are two ways glass is usually mounted in the vehicle.
Windshields, back lights and quarter glasses are mounted to the body shell to a mating flange where the inner and outer body panels are welded together.
One way the glass is mounted is with rubber weatherstripping to hold the glass in place.
Weatherstripping sometimes comes with strips of metal trim which is inserted after the glass and weatherstrip is installed. Sometimes these trim pieces actually wedge the glass and weatherstrip to help hold them into place.
The other way is where a water-tight adhesive is used to glue the glass in place. This adhesive takes the place of weatherstripping. Usually strips of plastic or metal trim overlap both the body panels and the glass. In this case the glass contributes to the overall structural integrity of the car. In most modern unibody cars this is the usual method of mounting glass.
