Removal of Rear Door Triangle Glass on Sedan - NEED HELP!

So, I just bought my 325i two weeks ago. The rear triangle windows on the sedan model only have a very weathered and cracked seal/gasket. I bought replacements for $12 each. The gaskets on the car are otherwise perfect (with the exception of the wiper cowl, which I already fixed).

I am trying to remove the rear triangle window glass to swap these gaskets out, but it is complicated. I found somewhat of a how-to for a different generation/series BMW. Some of it helped.

I have the door panel off and the upper door gasket loose/pulled. The screws holding the trim to the sheet metal frame are out, but it still doesn't move much. I really could use more guidance. I already broke a window switch, which looks like it was half broken the last time someone pulled the door panel off. I am getting a little frustrated and would appreciate the aid of someone who has done this. I had very little luck locating any other threads.

There is a pic of the current gasket/window below. Thanks for reading.

I hope that isn't right. Otherwise, this is a nightmare.

Now that I have taken it all apart, I can see it is glued. I did find a decent solution. I carefully scraped all of the rotted rubber with a plastic trim tool and cleaned it up with a very wet magic eraser. There is a tiny line on the window all the way around where the rubber covered for years. But at a few feet (in other words, to all others but the ones who would know), it looks stock and good. This is the best solution for a 10 year old car; I am not going to have these windows ripped out and replaced. I tested for leaks with heavy water spay and, of course, it is still water tight.

I just accomplished this project

Let me tell you that it is a bitch to do without cutting out the glass. The seal that the OP is talking about is called a frame in the factory service manual. This frame is made from very tough plastic with a rubber lip seal. I found that the frame is partially glued at the bottom edge from seepage during the original install. I removed all the weatherstripping, door panel and the steel window guide. Then I used plastic pry tools to lever out the frame and then cut the frame near the bottom edges and used needle nose pliers and yanked with significant force to remove the last piece. Then I lubed up the frame with silicone oil and worked the frame around the quarter window. This not easy, because the frame just will not stretch much. The frame once in, needs to be pushed into the glass edge to allow all the surrounding weatherstripping to fit correctly. The weather stripping is a pain on its own to work back in. I spent four hours on this damn thing and would not recommend it
