1968 barracuda s from Mexico

VIN and fender tag will not match in 1968. Sequence number is what you will find as the last six digits of the VIN. Eight digits of the VIN will be stamped on the block if it is original. Check the number on the top of the core support.

Automex fender tags are completely different. Not many codes and I've never heard of anyone that knew how to decipher them.

IIRC, vin is different as well as plate and location?? Can't remember exactly.
