ok , here is the deal. the series 1 motors ( both SC and NA) and series 2 NA motors have the same covers. but the series 2 SC motors are different. the GNX covers only have 4 bolt holes. myself , i used dupli color metal cast ground coat/ top coat for a gold anodized look. the base is a reflective silver and the top is a clearcoat gold.
here a pic of one of them
