Great question. You only have to have the warranty book with A p.o.p. in the plastic bag in the glovebox or displayed. Most people find an orpahn booklet that matches the year of their car on ebay or from the swapmeet and put it in the bag. The NCRS knows that obviously every car does not have its original booklet. The plate and stamps are not judged. Some people get plates made for their car and usually let it be known that is it not the original. I have seen people asked to withdraw from the judging field for a fake trim tag and typically you will not get through a Regional or National event without a deduct for broach and or stampings. And no the NCRS does not encourage anyone to fake anything, it is as in life up to the owner of the car to be honest about the situation. If the current owner did not know about the issue and takes the car to get judged they will be educated when they leave. Much easier to pay to have the car looked at before buying then to find out on the judging field. Just my opinion from having my own cars judged and having a lot of Corvette nut friends.
