I am with you Tim. I love original sheetmetal. I try to buy good used whenever I can. I even like good used better than NOS. NO Taiwan crap for me. Repro stuff from other countries makes me feel like I am putting together a kit car of some sort and not good old American Muscle. I know where there is a rust free (pretty much) 69 Z in the midwest but not sure he will sell! Its a very nice project car with a shell like you are looking for. Keep looking and good luck!
