Most jacks were purchased from the manufacturer by an outside provider. Does anyone know what other car uses the same jack as the Henry J? There is no jack illustration in the 1951-52 Henry J owners manuals nor in the Allstate manuals but it is illustrated in the 1953-54 Henry J manuals. The Darrin manual illustrates the same jack as is used for the Henry J. The full size Kaisers and Frazers use different jacks. The illustration shows a ratchet style U shaped bumper jack with a square base but with rounded corners and the wrench is the typical bent rod with the socket size proper for the Henry J lug nut and the other end shaped like a wide screw driver for removal of the hub cap.
