Sorry finally figured it out mods delete!! Bought a used sunrider soft top still new in the boxes and plastic of course I bought it out of town while in vacation. Well got ready to install it and of course missing mounting brackets. Well tried to order the brackets and of course out of stock and on backorder. Finally track some down only to be shipped day late so had to go to fedex in another city to pickup. Needless to say in mcdonalds parking lot installing this thing and thunderstorms blowing in on top of me. Get it installed after 45 minutes of cussing and 3 bloody fingers. Fit snug tight and looked awesome but got going down the road and the rear window keeps blowing out where it meets the door! What do I need to check and why is it doing that?

 

I did the same thing at first. There is a slot inside the plastic frame around the rear door and the window has an L shape that fits into that slot.
