Hi Dude, obviously I can't be sure, but I see no reason why the AMG Repro spoiler could not be fitted. You have a bracket in the middle (that we supply you with), plus a set screw on each side holding the spoiler to the front guard (there is one picture - second last) that actually shows that screw and its location, and you then have another self tapper (set screw) fastening the sides of the spoiler, again to the front guard.
Cost of shipping to the States, last time I enquired, was about $US200.00. Also, on a personal note and from observations, are you still able to fit those two plastic grille halves to the bracket on the body, or are they broken ? I hope I have provided some answers for you. Regards Styria
