Re: 67 or 68???
 

More details to look for:
1967 cars have a solid taillight with no vertical divide, '68 has a divide.
1967 doors and rear quarters (interior side) have painted metal for about the top two or three inches, 1968 door and quarter interior trim panels reach to the top of the door.
1967 bucket seat backs are painted metal, 1968 are plastic.
1967 VIN is located on the frame near the driver's door hinges. '68 is visible through the windshield on the driver's side dash.
