Yup, just is I thought, you have the short spoiler with no braces.....the same one that was on my 07C car. The hardware is very interesting also....your car has the standard center bolt (5/16 shouldered) and the small hardware is shouldered screws. My car has shouldered machine screws on the spoiler side and nuts on the valence side. There have been several threads on the spoiler and the hardware and this shows that there were indeed two different types of mounting hardware, screws and machine screws with nuts.
Thanks so much for your time and effort for fulfilling our request.
