A couple more tips for installing Sunrider when you have the dual top combo:
1. Rear window - there are also hard plastic tabs attached to the cloth material, on both sides of the bottom of the window. These get tucked into the hold-down channel, same as the bottom edge of the Sunrider top. Just did mine after removing back seat. Nice and snug now.
2. On my JK (not JKU), there are 6, 40 Torx bolts holding the hard top to the tub. After removing them, I sat them in the plastic bolt holder at back edge of cargo area. Not wanting to lose them before hardtop reinstallation, I screwed them back into the empty holes where the hard top normally attaches. Two notes:
a. There is a metal backing plate under the lip of the tub that the bolts screw into. If you don't put the bolts back in the tub edge, the retaining plates can come lose and get lost. One of my rear backers almost got away before I noticed the design.
b. On the JK, the window frame installed to support the Sunrider roof sits directly on the edge of where the front two Torx bolts need to go. If you install the front two torx bolts before installing the plastic window frame, the frame may not seat properly. I tried to put those two bolts back into their holes with the window frame installed, and the thread didn't align due to bottom edge of window bracket being too close to the hole. Those two bolts will go into a baggy, or get taped into the rear bolt holder tray.
Lots of words for some very minor items.
