I have A 67 HT AND I AM HAVING THE SAME PROBLEM.I THINK WE NEED A PERSON WHO KNOWS QUARTER GLASS


I had a bunch of difficulty on same car recently, but only on one side. What I figured out was that the small rail that is built into the car on the backside of the sheetmetal was pinched and not allowing the pivot roller to articulate properly. That was when I could even get all the rollers to stay in their places at the same time!
