IIRC they are just a flat piece of plastic. When you "clip" it into the dust/splash shield it forms into a scoop. If you're interested in trying to make a pair I'll see if I can remove mine and trace the outline on a piece of paper.
Thanks, but I’m still gonna move forward with the full brake duct, so I don’t need the scoops. But maybe somebody else might?
Hopefully I’ll get to attack this this weekend and I will post some pics.
