Hey guys... I need some help. As you all know the glass in the 81-91 Burbans is thin as could be. I shattered mine by slamming my door too hard and got glass soup in my door. I got it all cleaned out and Im ready to install a new window. I paid for a used window in good shape for 50 bucks. I got the used one out.. but cannot seem to get the wheels into the runner at the bottom of the glass when installing it. Can someone please tell me how to install the drivers side front window on a burban?
