I am restoring a hardtop and I am struggling with the installation of the quarter windows. I have searched the forums and tech manual and tried following the instructions but I must be doing something wrong. It can't be this hard! I have the headliner under the U channel. I have the outer chrome trim strip installed on the "B" pillar. I have the rubber seal on the glass, and well lubricated with thick soapy water (I don't want to get oil on the headliner). I am installing the quarter-window with its seal from the inside towards the outside, and I am leading with the pointy (rear) corner first, and moving it away from the headliner (the roof is sitting upside down and I am pulling the windows "up" towards the body seal) I can get the edge closest to the body seal into the channel and the lip is installed over the edge. I can get the lip started on the B and C pillar edges as well. I just cannot get the last corner of the window glass to come past the B pillar. I have cut the leather back so that it does not extend under the window seal. Can anyone here tell me what I am doing wrong? I appreciate any help you can provide.
