I am planning on putting a wind dam on mine after I get her out of storage. I'll probably just use some 1/2" plexi glass cut to size from the hardware store. Tired of the GF and her friends complaining after the sun goes down about being cold and the wind coming through...

How did you mount the aluminum channel pieces on there? Did you screw them in or use like a double sided tape? Not sure if you posted that and I missed it...

I have the same problem with my windshield too, but I don't think it is quite as bad as yours. I can still secure the window with the turn latches, but the top one barely locks onto the frame. Bottom one is still perfect.
