If you're interested in figuring out whether it's a '67 or '68 model, there are many tells. '67 has the VIN attached to the drivers door jam whereas '68 attaches it up on the dash. Look in the trunk to see if it ever had side lights. '67....no light.....'68 round light hole. It could have been welded up, but, you can usually tell if it's been done. K-members are different, wiper motors are different, steering columns are different, etc.....
