We got the rear glass installed. A couple of tips/observations.
#1, your not going to install a window that has not been bent to close to the proper shape. Installing a prebent widow is a tough job!
Installation procedure: run tape around the opening, so the rubber seal will slide over the headliner. If you look at the seal in cross section, it is not symmetrical. One edge is square, the other is rounded. Install the seal so the square edge is on the outside. We lubricated the portion of the rubber seal that slides over the top. Not a good idea. Yes, it facilitates installation of the seal, but it also allows the seal to slide off pretty easily. Lube the channel the window slides into and install the window from the inside of the top and work on the outside. Start in a corner, then switch to the other corner. Takes a lot of muscle! We needed three people, two to muscle it in, one to hold the top in place. Two just could not do it.
At some point, the design of the side glass seal has been changed. The new style does not like to follow the bend in the window opening, it flattens out. To compensate, the factory slits the seal and installs a piece of 1/2" (or so) round rubber. This does not work for diddly. It is way to thick and holds the glass away from most of the length of the glass. If you purchase new side widow seals, try to get it unmodified. I think unmolested seal would work better. I inserted a small piece of plastic in the seal to give it the proper bend and keep it from collapsing. Have not test fitted the top, so do not know how well it works. I'm pretty sure it will be better than "as modified". If I'm happy with the results, I'll post more detail.
