The rear window in my '35 Fordor is really fogged up bad and needs replacing. I got new glass cut and ready to install. I thought this would be an easy job until I tried to get the old glass out. It is so bonded in place that I could not get it out without breaking the glass which I would rather not do. I decided to hold up on this job until I had a better understanding of how this should be done. Since then, almost a year has passed and this has still not happened. Therefore, I can be of no help to you on how this is done, and like you, will be follow this post hoping for some good ideas/answers.
BB, My apologies if I seem to be hijacking your post.
