It came with a round fixture that had a depression stamped in the center to locate and center it in the center hole of the spare wheel, secured to the wheel by means of a threaded stud through the center hole, a smaller round plate on the other side, all secured with a bolt and wing nut passed through holes drilled through the centers of the fixture and plate. The business side of the round fixture had three short lugs with domed heads, similar to a carriage bolt, that engaged with three curved "lollipop on a stick" slots on a ring welded to the underside of the fuel can. The fuel can was secured inside the spare wheel recess by locating it on the three lugs and twisting it a few degrees clockwise. Twisting it counter-clockwise allowed it to be removed from the recess.
