Aero kit Q's and third brake light?
 

I just recently bought an '06 G35 Coupe 6 MT. Has every option as far as I can tell except navigation.

The only thing I'm a little confused on is it has an '05 spoiler(I've seen 3 '06 Coupes with this spoiler on for sale when I was looking for my car). I also have a third brake light in the rear window. Does this mean I don't have the underbody aero diffusers? I took a quick look underneath, and I didn't see any obvious plastic pieces.

Does anybody have a pic of what they look like on a coupe?
