Have tried to find more on the horrible vent window work and parts. I am wondering two things on the windows.....does anyone offer a kit of the rubber and channels for the windows, and also has anyone figured out how to lubricate the vent window, to ease its operation. I assume that the upper and lower shafts could be lubed with something. And of course the regulator. But, I have not found a discussion on this issue. Anyone had any luck with limbering up the triangle of glass that causes so much trouble. Thanks for thoughts.
