I installed my top just prior to reading your experiences. I can certainly commiserate with you. I had a hard top on for the first year that I owned the Jeep but decided I wanted to experience the wind blowing through what hair I had left. I just happened to be looking through Craigslist when I spotted a Supertop NX for sale. It had only been on a Jeep for about 3 months and was, for all intents and purposes, brand new. Since it had previously been installed, I was saved the experience of assembling the framework which the previous owner assured me was a pain in the hip pocket. Also, the PO had thoughtfully discarded the assembly instructions but assured me that installation was “intuitive”. Actually, installation wasn’t all that bad with the exception of those damned screws in the door surrounds. Three of them finally threaded after several hours of twisting, turning, and cursing but the fourth one absolutely refused to thread. Then, - - - a light went on in my head. I remembered that when I bought my Jeep and got it home, I discovered a couple of strange looking, hinged, plastic thingeys with large knobs with threaded shanks clear in the back luggage compartment. Those were a pair of original Mopar door surrounds with the large attachment screws (with tapered ends on the threads). After about five minutes, which included removing the three screws which I had managed to get installed, I had all four door surround screws installed. Why Bestop would sell a product which included four screws that are practically impossible to install when all they had to do was taper the ends is beyond comprehension.
There, that rant helped.
