Thanks for the photos, I think my window rubbers are slightly different to yours, where my window rubber butts up to the main frame it is just a u channel, I will get a photo on here of the cross section, but I got them from Richard so would think they are the right ones. Do you glue the rubber into the U channel? All I was thinking of using to hold the quarter light and main window frame in place is Tiger seal, its all that's holding the front spoiler on my VW transporter + it never sets hard, I was also going to run a bead of it under the external angle that sits on the top of the door. Masking it all the door first of course.
