Further to Hotdognz' message...I had Pro Racks fitted to my JKU in Jan/Feb of this year through Altapac in Newcastle. Can't recall what brand of tracks they used but might have been Yakima (see pics). They did them pretty well exactly as you have them (great minds think alike), by placing the track on top of the raised roof rib - except on a 4 door in a single track. They look clean, are easy to remove and position/setup. I also have the Pro Rack 4 x board snowboard carrier and 2 x bike racks than can fit (just) on either side. It all works really well and all lockable. Have carted snowboard and skis 14 hr round trip to snow. Couple of mountain bikes. All good. Cost for the pair of racks and tracks installed was around the $500 mark from memory.
