I have the glue in front windows and have been having alignment issues for a while until the metal rail piece that is glued onto the back of the glass has fallen off and the window is loose in the track. I'm planning on replacing all the door/window gaskets, felt and bushings and reseat the glass. I'm concerned about how to have the glass in the right possition in terms of front/back and angle when I glue them in. Any help would be greatly appreciated.
