*****Guard kit 12-755-91 must be used with guard kit 12-755-70 or 12-755-72 to comply with EEC standards for avoidance with hot surfaces.  Kit includes wire guard and two
            shields, plus instructions, although all parts are not necessary for every muffler configuration shown.  Wire guard covers exhaust manifold;  shields prevent contact with
            manifold periphery

       *Includes angled oil fill tube and dipstick to clear muffler, plus mounting bracket and hardware.  Muffler outlet is 5.5" above valve cover.  Outlet O.D. is 1.25".
