I have two Trailer hitches. One is a light 2 bolt and the other a heavy duty 6 bolt with bumper plate. Both attach to tow ball directly without a receiver channel. The hitch is all steel and bolts to the underside of the frame and rear bumper. The main crossbar on both is 15" wide by 1/2" thick and the tongue is 2" wide by 5/8" thick. The crossbar hole spacing is 13" . The hitch is in very good condition and was used on a Plymouth Road Runner to tow a 2,000 pound boat and trailer.
