I need the rear emergency brake cable guide and bracket from a '66-69 Riviera. These are the little gizmo that the brake cable passes through in front of the rear wheel. I need both sides, plus one of the hooks that puts tension on the rear cable, just inboard of the guide and bracket. The guide and bracket is bolted to the underbody with a single screw with a 1/2 inch head. Mine are very rusty, so I am looking for rust-free parts. Any help is greatly appreciated. Jim
