Our OEM rack use oval mighty mounts that you need to replace the mounts included with the kits for round or square bars. A quick look on the Yakima site and it seems the Hullraiser, Hullyrollers, Kayak Stacker or the Landshark Saddles would work. I don't know the part numbers for the horizontal mounts offhand you would need for our bars, but a search for mighty mounts will come up with something.
