I took all of the glass out when I had the car painted. I kept all of the parts for each side separated and tagged so I would be sure they would go back in the way they came out. It is all the original glass and tracks that came on the car and it was all in proper working order when I pulled it. If I would have known reinstalling them would have been this much grief, I would have left them in and masked them off when the car was to be painted.
