Spotting a fake

Where the VIN numbers are stamped on the car depends on the year. Most all cars 1969 and up have the VIN number stamped on the trunk lip. Think upside down...you stick your head in the trunk while standing on the ground and look back at your crotch, sort of up under the lip of the trunk rim by the lock mechanism. This may not be true with 68 and older cars, and may not be the case on a plant by plant basis, but I believe the Detroit built cars are all this way. 1968 and older cars may not have this, and the further you go back the less likely it will be that any numbers are stamped anywhere but the VIN tag, which is on the door jamb before 1968. My 67 Cuda and GTX do not have any numbers stamped on the radiator support or anywhere else. If you can get under the car, part of the VIN is stamped on the trans on 69 and later cars also. Post the year and model of the car and maybe the more informed owners of that particular year and model can chime in with some exact locations. Geof
