I am TRYING to install the rear window on my W126 ( 1982 300SD). I have a new seal. I installed the glass to the glass channel, and the trim in its channel, but as soon as I pick it up, the trim pops out of the channel. The seal seems just a little loose. When I fit the glass and seal to the opening, it looks like it should fit. Its the trim that is beally getting to me. I was so frustrated, I had to walk away and consult my buddies here on the MercedesShop. Anyone in Bel Air, MD want to install a rear glass? I am getting desparate!
