Window question

OK, pictures help. This is my '68 cuda, yours should be the same or similar. We are looking at the right side. On my car and on your car- that hole in the door allows you access to the allen bolt seen here, or maybe on your car a phillips screw. This screw along with others allow you to adjust the position of the "A" frame to the body/ weatherstrip.If I were to put an allen wrench through that hole to make an adjustment, the allen bolt itself is about 1 1/2" inside the panel. Hope this helps.100_2402.JPG100_2403.JPG
