I am a bit surprised that there is not a GM approved replacement parts maker for rear fenders (maybe there is and we just dont know)as I think the trucks are every bit as popular as some of the cars out there that the reproduction USA stuff is being made for. Mar-K type company would be the type of USA mfg. outfit that already is set up with freight shipping and quality control that would be good. I have decided to let the bodyman work on the old original steel ones. They will need some work but they are real.
