You're missing my point. The side you replaced is irrelevant.
No, I got the point. What I didn't mention is that when I replaced the old glass, I not only cleaned the channel, but also wire wheeled it with my 4 1/2" grinder, then used 3M adhesive remover to clean it, then inspected it. I used new rubber/cork imbedding tape from Classic Parts to install it with, and I've done both windows (the first one, I did twice when I accidently put the glass in backwards, which needed another new pane it was set in the rail so well, I had to crush it to get it out. The glass, that is, not the rail.) I've read the shop manual, asked questions here and thought it out before I even started the first one. You have a good point with what you're saying. But you are assuming that I didn't know or do what was necessary. It was as clean and straight as new when I installed it, and it lasted all fall and winter without any problems. But thanks. Lee
