A radius plate structure for use in aligning a vehicle wheel resting thereon has a bottom plate member and an upper plate member positioned in overlying relation to the bottom plate member and connected thereto. A bearing cage is situated between the bottom plate member and the upper plate member and permits smooth rotational and translational movement of the upper plate member. The particular connection permits rotational movement while restricting translational movement to front to rear movement of the upper plate member relative to the bottom plate member. Rotation stopping connectors, such as a pin extending through an aperture and received in an elongate slot aligned front to rear, extend between the bottom plate member and the upper plate member and lock the upper plate member relative to the bottom plate member at a selected amount of rotation whereby only front to rear translational movement is permitted.
