Larry, I purchased this kit from Chief and absolutely love it. No knot tying required, just hook both ends and pull. They release just as easy. You need the JK TD-H part number for high wing.

It includes the ropes but not the corkscrew tie-down hooks so I purchased three of these specifically for parking off-tarmac.
