68 Nova quarter glass question

[Schonyenko2]

There is no real way to make them work well. If you roll them down to where the glass doesn't show, they get at a bind angle and don't come back up. It is a bad design. Many Nova guys who replace the rear seat panels don't cut the holes for the window cranks so there's no handles for people to roll down the windows.
My 2 cents, don't fight it. Leave them up.
