2wd5spd

so im starting the body work on my truck. i bought a fender and a door off a guy that is parting his truck out. i got both for $100. His truck had the factory black fender flares on it. i got the flare that came with the fender, and went ahead and bought the other ones. the only problem i have is that i dont have the little green plastic peices to mount my other flares and i cant find them anywhere. does anyone know where to look? should i try the dealer?
