Stylin n profilin made this neat fender set for Peterbilt trucks. It wasnt only his reasonable price, but the fit looks oem style and you can keep your existing hood. Shapeways has some fenders, but I like these better. Anyone know if he's still around? last comment on his vender page was back in 2013....
This was his vender listing:
