My first car was a '69 Grand Prix Model J.  Yeah, I want to be a kid again.   What are the best books to find part numbers, engine codes, date codes, colors, options, etc. for a Grand Prix.    I have a 1967 and 1970 Vette, now I want to find a 1969 Grand Prix.   I want to find a car that is as close to "correct" as possible.  What should I be wary of?  There are a lot of scammers in the Vette restoration biz.  What publications have parts?   Any info would be greatly appreciated.  Thanks.
