Nah you're right, I've pushed windows out of 1200s about 5 times, and you never can tell what is going to give first. The rubber from the body, or the rubber holding the window. Now that I think about it some, I think on all but one occasion, the rubber and window came out in one piece.

ps. When I bought my rear window rubber from Spectrum rubber (Dunheved), it came in 2 versions, one for the stainless trim, and one without. I don't know if this difference is still available, but the rear rubber was great. I had a Nissan factory rubber for the front, and it wasn't a great fit.
