Wondering if anyone knows of a front spoiler that is a good fit and looks factory

Saw a plastic one the other day it didnt have the taps at the guard end and was made straight si it needed heat work to make it contour correctly and when the shape was somewhere there the screw lugs needed adjustment. He also bought a Fiberglass version that was a shocking fit. The manufacturer told him his front was out of whack....which it wasnt

I know there are fiberglass versions out there but which one works?

Surly now someone has managed to make these and get them right??

any advice would be appreciated
