Chipping away here guys. Original owner of the car says the magazine was kind of a DIY type rag. He tried real hard to recall the details of the photo-shoot and thinks the photographer said it was going in "Chevy Power" Magazine.
I did search ebay, but couldn't come up with anything earlier than 1973, but is was great to verify there was such a magazine! Pages form Chevy Power have already been posted on Yenko.net

Any help finding the late 1968 or all of 1969 is appreciated!
