Using the valve cover mounting bolts, these handsome Chevrolet chrome looms are positioned along the valve cover to hold the wires, up to 8mm, in a neat parallel arrangement. The epoxy-coated Bowtie Emblem is centrally located for maximum visibility. The wire holders are opened and closed individually with a patented nylon wedge to permit the chrome tops to have a smooth surface free of screw holes.
