Proform's GM licensed Chevrolet linear wire looms use the valve cover mounting bolts to position them along the valve cover to hold the wires in a neat parallel arrangement. They feature a handsome chrome finish with an epoxy-coated Bowtie emblem that is centrally located for maximum visibility. The wire holders are opened and closed with a patented nylon wedge to permit the chrome tops to have a smooth surface free of screw heads.
