A pedal for a vehicle has an integrally formed clevis, a central portion, and an integrally formed relatively flat foot engaging section. A lightweight, one-piece, extruded aluminum tubing with a thin wall and a round cross section is bent at an acute angle to form a clevis at its upper end and is bent at about a right angle at its lower end to form a foot engaging portion. A hydroforming process forms the walls of the clevis end and the central portion into a rectangular cross section and forces the walls of the lower end together to form a relatively flat, smooth, upper foot engaging surface and an undersurface with longitudinal ribs. Hexagonally configured apertures in opposing walls of the clevis receive a bushing having the same hexagonal configuration. A cut-out section communicates with the aperture in the two opposing walls, and the bushing is secured in the apertures by forcing together the walls adjacent to those with the apertures to close the gap in the cut-out sections. This action causes the walls of the apertures to be received in notches provided in the bushing.
