Thanks for the response and advice. The videos confirmed for me that I can do it. The confusing part is that the window separated all around except for around 12 inches at the top center and when I try to center the window the bottom fabric will not line up with the original glue track. Is it possible that the fabric top shrinks? I released the tension and tried to stretch it down with little luck. The only thing I can think of now is to cut the glass out and try to re-center the window in the hole. I'm afraid that will weaken the repair if there is less fabric to glue to the glass. Any advice will be appreciated. MikeE
