I think it's more like "Yes we did"!
Well, today I FINALLY found the local sign shop! YAY! They want 20 bucks for a 4x8 piece, so I think I will pick one up. The pieces I have are at most the size of my current air dam, but I would like to extend it up the grille like you did. Also, I didn't have much freedom cutting it since I only had about an inch extra.
How did you attach the flat piece of metal near the wheel wells? And about how much did the metal cost?
