Cougar Eliminator hood scoop? Those look right, are they from a different scoop? I would help you, but don't want to remove my hood scoop. I think diameter of the course side of the studs might be critical, unless you epoxy them in?
If I could get to mine, I'd take some pic's. It's in the far corner, to the right of the "Canadian" flag...on top of that gray box.
