That link is only for the windows and the skin...the skin also isn't sailcloth so i'd pass. But if you go that route you'll need the factory bows, header, door surrounds, tailgate bar and retainer clips. Look at the bestop supertop NX it's a complete kit but it's around $750-$1000 depending on the doors you have.
There's also frameless tops like rampage's frameless but you'll still need the header, surrounds, tailgate bar and clips. I think the rampage sailcloth top is around $400.
