So do any of you Cov. owners have really loose 1/4 windows? Ive taken of the rear 1/4 panels out of my 88 Gt Cov. to see how to adjust the windows but I just dont see anything to adjust them. When the windows are all the way down they are loose as a goose. They still go up and down but the drivers side is so loose that it doesnt seal right when its all the way up. Anyone have or had this problem or any ideas to fix this?
