@LONGJP2 @AjRagno @06TJ35's thank you for all the help, really. I called bestop a couple hours ago and they received my emailed photos and think it is their supertop nx that is missing pieces. They sent me the installation instructions w/parts list:
https://www.bestop.com/wp-content/uploads/Installation Instructions/BDKW_54721-INS_001.pdf. After looking at that, I definitely don't have door surrounds or tailgate bar. I also have zero hardware (screws/fasteners). I'm guessing, including tax, $380 for door surrounds and tailgate bar. Not sure if a top arch is needed vs recommended, and not sure what all the screws/fasteners would cost as well.
I've been watching youtubes on bestop supertop nx installations on tj's and what I have looks different, though (see second photo attached). First, the top as given to me is one piece, with the bows attached as depicted in the photo I'm attaching. If it was a bestop supertop nx, it should be two pieces/bows, with each bow attaching separately to the sport bar/roll bar (aside: is it possible the prior owner just fastened these bows together for convenience while storing?). Second, if this is a bestop supertop nx, why wouldn't i have the bestop pivot brackets already installed on the sport bar (who buys a $1250 top and then never uses it)? Third, did bestop even make a khaki diamond LJ soft top?
@AjRagno seems pretty confident it is OE LJ soft top, but again, my soft top is currently all in one piece with the bows fastened together. My understanding of the OEM is that it is also two bows attaching at two different places to the sport bar (based on stryker youtube video
)
Because this is a rubihara with only ~80k miles, I would ideally want to have the OE top in khaki diamond, but a quick google search returned no khaki diamond LJ windows at any price. But I'm stubborn and will hunt it down.
Attaching another photo I took of the header-end in case it is somehow useful
Thanks again for the help!
