Sorry to see that! I just cringed when I saw the first pictures. I am just guessing here, but I have a new rear window and set it in the channel. I noticed that the glass did not lay down evenly all the way around. It would hit in one spot but then wouldn't contact again for another 12" or so. The gap was only 1/8", but it was a gap. I was thinking I may have to put in rubber shim strips along with the rubber blocks to ensure it hits evenly everywhere and avoid putting stress at one spot. I am no expert, but that is what I was thinking. Is there a procedure for laying in the rear window?
