Right now let's go camping - that's a bed
I've been searching for the glass channel too with no luck. Mine had gone wiggly and jammed the windows I ended up stripping them down and warming the plastic runner with a heat gun over a length of angle iron of a similar thickness to the glass - and it worked. The glass slides nicely now. If you're careful it might work in situ with the glass still in place.
I was getting desperate and I nearly got some of this to try with the idea of cutting one channel off, it would work out quite expensive though.
I did find single channel in short lengths but the outside thickness was just too big and jammed the glass up.
