Ok, guys, so it's been a while, but I've now replaced not only the glass, but also the channel it rides in and the front weatherstrip in the front channel (back of the vent window). I was going to replace the flexible section on the top/back of the window, but when I realized I need to move the clip off the old w.s. to the new one, I decided against that. Actually, it looks like the w.s on both doors has been replaced already, and the rear wasn't worn down to the metal like the bottom of the front channel was. I now have a small problem (the old weather strip now leaves a 3/8" gap at the top/front of the window), so I'll probably end up replacing it anyway. Another problem I'm seeing is that the old upper metal retainers which stick into the top of the weather strip to keep the top of it from falling down when the window is down, have lost their little triangle 'punch outs' which attach them to the w.s., and I can't find replacements ANYWHERE! (yet) If anyone knows where I can get some of these, please let me know. I'm not having any luck. Thanks, Lee
