That is some good info/documentation to have for people/prospective GTO buyers to see. I don't know if there is anything out there for the 2004 kit because it was a last minute put together by GM to help push the last of the 2004s off the lots. Nonetheless, I paid $500 at the dealer parts department for my 2004 kit, which was the grills, the spoiler and the 2005 hood. This was absolute theft on my part and I can't think of a better deal I have ever gotten on parts like that.
