Thanks to a buddy of mine for modeling and printing these extensions I asked for. There's was some work involved to get them to sit nicely. With textured paints (wrinkle and then hammered) and multiple coats of paint (semi gloss, matte clear) I think it's pretty close to matching the fender flares. Used the leftover weatherstrip from the flares to help match it to the flares. Waiting for them to dry some more and attaching with 3M two sides tape.
