OK, here is a new mod I did to the trektop to turn it into a bikini top.
ok, so what I did after the top has been fully installed.
4 ball bungee cords or 2 buckle straps
4 pieces of 1' long double sided velcro (velcro that can bind to itself)
Step 1, open rear doors
Step 2, unhook rear window from J channel and unzip it
Step 3, Open tailgate
Step 4, roll rear windshield down with a towel to protect the window from damage. (I placed the towel on the inside and rolled it)
Step 5, use 2 velcro straps to secure the rolled rear windshield on the tailgate bar
Step 6, pull the little plastic tabs off the body so that the rear side windows are hanging
Step 7, use 1 ball bungee cord and slide it over the pole that runs across the rear. have the plastic portion hanging, then loop the other bungee ball over the roll bar in front of the cross member, then hook the hanging ball through the loop of that bungee cord
Step 8, repeat step 6 and 7 on the opposite side.
Step 9, make sure that the rear portion of the top is secure and wont slide off or snap off. If the bungee cords you have don't come with limiting sliders, I suggest you use twist ties to secure them.
Step 10, similar to the rear windshield, use a small towel (I used microfiber towels) and place them on the inside of the window then roll it up nice and tight.
Step 11, you will notice its not a straight roll and it kinda twists to the rear section of the jeep, so follow its normal lines and let it twist to the inside of the cargo area and using the velcro secure it to the roll bar.
Step 12, repeat step 11 on the opposite side
Step 13, enjoy the final product and your new bikini top that can be turned back in less than 10 mins to a trektop.
Note: in this picture I do not have the rear window rolled and secured, I just let it go under the jack and I left it like that for a while.
Note: I kept the bungee balls on, even with the trektop fully installed.
This has been done to a 4dr and I am not sure how it works or looks on a 2dr...sorry 2dr guys, someone can try it and post.
I will try to redo this and take more pictures that detail every step.
