I am trying to find out information about the high mount wing on my Chevy Cobalt SS Supercharged. What I am looking for as far as information is: 1) Is the blade of the wing hollow? 2) Are the 2 mounting pieces hollow? 3) If they aren't is there like a channel through from one ened to the other at least?

I have an idea about a mod but I need more info before looking further into doing it. I would appreciate any help with this.
