Owners of 1936 Fords can only mount their spare wheels with the valve at the top, as if they don't, the metal cover will not sit correctly. The hubcap on this cover is hinged at the bottom to gain access to the lock. If the cover is not mounted with the valve hole at the top, the hubcap would sit at an angle. The problem of where to place the valve is only a concern to owners of 1932 to 1935 Fords.
