The rear window had been installed on the tailgate bar, and the tailgate bar slid into its mounts on the rear of the Jeep. To get the rear window zippers started, we pulled the two sliders all the way down on the driver side of the rear window until we could connect the two sliders with the zipper’s catch pin. Then while holding the top of the rear window up with one hand, we used the other hand to pull the top slider up, over, and down, zipping the entire window closed. Take care to not catch the zipper on the two layers of fabric it’s sandwiched between. After making sure the tailgate bar is centered securely in its mounts, we tucked the plastic flaps on the bottom of the rear window under the tailgate mounts.
