The lock is correct and a nice accessory to have, but the hook is incorrect. Someone has made that and reformed the hanger on the underside of the truck to accept the hook. The hook should be a "T" shaped hanger with tread on the long part which hangs down to go thru the the actual carrier. The part under the truck should have the two sides spread far enough apart for short part of the "T" to fit in the two grooves and the long threaded part of the "T" to hang down between each side. It goes through a hole in the carrier and the nut, or lock, goes on that long part.
