please correct me if i'm wrong, but even with the vin, you cannot 100% confirm weather the car is a true SS or not, should have 1847 in the vin for #'s 2-5 (if i rember correctly) but it is best to just check the car out well, and make sure all of the SS "parts" are present (auto on the floor, "SS" fish scale patters on the dash, in the corners of the speedo, in the outside lower trim, in the rear panel inserts, etc.) most "clones" use incorrect parts, or dont replace every part. i have seen many '63 clones with '64 SS center consoles and door panels, and a lot of clones with out the "fish scale" patterns in the speedo corners, incorrect trim, incorrect bucket seats, etc. etc.
