With the soft top that you have, you already have the windshield channel.
The rampage kit that you have shown is a bikini top, with a windjammer(window behind front seats), and a tonneau cover.
You need the soft top channels around the body(which you already have). And the windshield channel. The rest of the tie-downs on that kit are velcro. It isnt designed to be run with doors, but you can use your doors with it, the tops of the doors wont be touching anything and therefore will vibrate violently in the wind when going down the road.
You have to take off the top and all of the top hardware, except for the channels, and this item will fit.
