Hello.

On a 67, the number is stamped on the body in three places. If you open the hood and look on the driver's side, you will see 6 bolts holding the edge of the fender to the car. There will be a step in the edge of the fender. The number is stamped there. The other two places you have to remove the fenders to see. On a 68, there is a tag riveted to the front of the dash, right up to windshield. It is also stamped in two places, but again, you have to remove the fenders to see it. The local police can run the number to see if it has been stolen. Hope that helps.
