Bestop question

Well..I'm gonna revive it again. Now...I know the fabric is gonna stretch when it heats up. BUT...here's my problem. My windows don't want to fit. There's a huge gap between the zipper on the window and the zipper on the top.




Those pictures are with the window zipped on one end. WTF am I doing wrong here guys?

 

yea wait for it to heat up, then zip the other side just a little, enough to hold the window, then zip up the other side a little, and go little by little on each side

 

Take the tension off of the top. You can leave the front corners on but I unhook the back corners. Zip the side windows on. Then you can start hooking everything back up working from the sides to the back.

 

Is it gonna move THAT much? Seems like a long way to move.

 

The problem is that I can't get the zipper to reach. If the front zipper is engaged, the rear zipper is like 2 inches from touching, and vice-versa.
