[KIQ350]

Thanks for the input everyone. I'm going to go with gluing it back together.

I removed 2 bolts that hold the regulator in place and removed the U channel from the door. The regulator and U channel look to be in pretty good condition and the rollers still have a light coating of grease.

I also removed the front quarter window (lost a washer in the door...d'oh...got to try and fish it out) and inspected the front channel. It's felt from top to bottom and looks to be in pretty good condition. Is there a way to lubricate felt?

Next I'll remove the rubber from the channel and glue it back on the glass, then slide it all back into the channel (with glue) and let it dry overnight. I am NOT looking forward to re-attaching the channel to the regulator.
