Does the OEM rear spoiler extension come with a template or instruction on how far from the spoiler edge to mount the piece? I looked closely at some stock photos of the Evo 9 MR cars when they first came out and that gurney flap is not attached right along the rear edge of the spoiler (like many do nowadays). I know for the OEM front license plate bracket for my 9, Mitsubishi actually provided a template/instructions for exactly where to drill the holes and line up the piece properly on the bumper cover.
