The upper back seat of a 68 is slightly different in appearance than the 67. The 68 has a slight indentation to the seat on the passenger side where the striker post is mounted to the upper seat. The 67 did not use the striker post/latch assembly to secure the seat in the upright position. If you know what to look for the two seats are noticeably different in appearance.

Thanks for the facts on the seats?

Seat found....Thanks....!
