Mounting (welding) to the underside of the frame on both sides, then extending outward (to the rear) through cut-outs in the tail body panel is what I was thinking of doing. But after seeing the diagram/picture of the Elio suppliers that illustrates where the muffler may be located, I am wondering if that will now work.The swing arm will not be the place to locate a hitch... it will have to be mounted to the frame/cage.
