Rick, I have not spent a lot of time on ebay lately and had not seen or heard of the auction. As for the parts themselves, it's pretty hard to judge anything by those photos. It would really be best to see the parts in person. The parts that are in GM boxes or packages certainly seem like they would be NOS. The headers? If they were NOS, it looks to me like they might be repainted or Jet-Hot coated in black now. To me, that is kind of a shame.
