Definitely a dealer demo. First thing is to get that SS emblem on the trunk. They tend to rust there. The hood is easy to adjust. Make sure to lube the hinges. Loosen the front bolts and just snug them both sides. With the hood loosen the rear bolts and pull the back of the hood down and tighten the bolts. Close the hood on its safety catch and check that the rear of hood is not too tight. You may have to loosen the front bolts and pull the hood up. This may take a few trys. A Chevelle air filter will fit. New valve covers. An awesome car. I wouldn't mind having it. NICK L72
