A male member includes a first end movably disposed in such cavity and a second end. An aperture is formed through such male member first end. A portion of a spherical shaped member is disposed in such aperture. A pair of shaft members extend from outer surfaces of such spherical member. A portion of each shaft member is disposed in respective side wall openings. Each shaft member has a flat surface formed thereon. A race having a portion thereof disposed in such aperture and secured to such male member. The race inner surface is disposed around the spherical member. A pair of wedges, a surface of one wedge engages one of such shaft members flat surfaces and another surface of such one wedge engages a flat vertical surface formed on one side wall adjacent a portion of such first opening and a surface of the other wedge engages another of such flat surfaces formed on such shaft members and another surface of such another wedge engages a flat vertical surface formed on a second side wall adjacent a portion of such second opening.
