ggpuck123 - There are different methods of glass installation, some rope it on by useing string layed into the rubber channel then pulling the string to bring the rubber lip over the glass.
I had a local glass shop install mine on a Bennett 966. They first put the rubber onto the door then layed the curved glass on top of the rubber and sprayed the glass and rubber with lots of foaming glass cleaner, then used a "bone", a glass tool that is shaped like a plastic knife to work the glass under the rubber in a clockwise direction.Worked for them as I'm sure I would not have had the same good fortune being a rookie to glass installation.

There are small clips that have a nail type head that pokes through the rubber on your window...then a piece of flat spring steel goes over the nail to keep it from pulling through. I was lucky enough to get these small nail clips with the trim I bought from Tom Buckles on this site.

Good luck
