This would get you close from ZCCJDM. I have this piece and am installing it on my car, i've trimmed it and done quite a bit of work to stiffen it (I always expect work when ordering any fiberglass piece). Not a bad piece but not a great piece of fiberglass either to be honest, it's the best available from what I gather if that's the air dam you want.
The glass was a little thin for my liking even with the additional layer of glass when I ordered it, but it's still a workable piece and the shape/front is great.
