Yes, and latches for seat backs. Before 67 the top member of the seat back frame was round tubing. When they changed it to square ( and punched holes for head rests ) it got about 1/2 inch shorter. They did tend to use up existing stock but majority of 67 seat backs will have the later design.So 1968 seats had holes for the head rests?
Like mbaird said, the 67 buckets are at bit more dressy. Heres our 67, I have 69s as well but nowhere as "dressy" as the 67.
Our 67 has optional headrest.

Can you measure the distance between the "posts" that go into the seat?
Heres some info from another member.
