I worked at a restoration shop and the Secretary of State Police came in to do an audit and found several dashes off cars to be done. They were going to confiscate one out of a 68 because they could not find the VIN numbers on the body that was sitting next to it. I had to explain to them about the VIN and SO numbers, they had NO idea! After I did, the cop in charge asked me if I could teach a class to his other deputies so they knew about cars before 1969...
