Ah, what to do with the rear window on a nice day. Rolling sucks and leaves marks. Taking it out is a pain as well as finding a place to store it only to have it rain on your way home from work. But, it does fit nicely between your soft top and the roll bars. Problem is, at 50 MPH it blows down.
Take velcro (the kind with the sticky backing and cut 2 4" strips. In the end you will need 4 strips 2 male and 2 female. Now take the retainer bar at the bottom of the window and turn it towards you 1/4 turn. You should be looking at the bottom of the bar. Place one Female velcro strip on the bar about 1/2" inside the plastic retainer flap. Do this on both sides. Now take the Male strips and mount them perpendicular (following the framerails of the Jeep) onto your sound bar.
When your ready, unzip each side all the way to the top corners. Carefully roll the window into the Jeep and wiggle it between the roll bar and the soft top - make sure not to fold or crease it. Now, as you snug it up, turn the bar 1/4 of a turn so the velcro seats.
What you end up with is a nicely stored flat window that will stay put as you cruise. On the downside, you will get some rub marks near the lower corners of the window from the roll bar but unlike the rolling straps, they are not in your normal vision and shouldn't interfer with driving.
I have pictures but as it's my first day on the forum don't know how to post them yet.
Hope you found this helpfull.
