I just want to thank Chris for starting this great discussion. I learned a lot just reading through it.
A word about documentation: I went through an AACA judging school last year, mainly for my own edification. While their judging is not model specific, they are very strict about what they accept for documentation. It must be information from the manufacturer.
If there are any recognized Camaro judges out there, it would be great to know their standards. Before the juding school, I would have said they should have told Chris those things. But I now know only the head judge is supposed to talk to the car owner, and that is done only if the owner asks.
Also, after hearing these guys say what a great looking car Chris has, I'd love to see some pictures! I remember 68 well. Green was cool in 68.
