I just traded my '85 tired 305, slipin 700r for a '88 350, 4 speed, all crank windows. The question I have is the rear window doesn't go down all the way it has about 3" sticking up. I removed the panel to see if something was in a bind, it all looked OK. When the window is cranked down as far as it will go the rollers that slide in the channel on the bottom of the glass are all the way to the end. Is this common for crank a window or is there a way to fix? Thanks Chas.
