Installing the rear windows was similar to the door windows except gravity was working against me. This meant I had some challenges trying to figure out how to clamp the window to the flange. Following others lead, I fabricated some scrap aluminum "fingers" to hold the window in-place drilled holes around the window cutout to cleco the fingers to. Unfortunately, I could only put fingers around about half the perimeter of the window so I opted ot use a lot of duct tape. It really looked ugly but it got the job done.
