For the Strato buckets & bench seats, headrests were available starting in 1966. The same design was used in 1967. The seats themselves must be equipped to accept the headrests. That is the 1st design.
The 1968 - 1972 headrests (2nd design) are generally the same each year, but there are differences as to where the lock notch is along the shaft of the headrest.
So, what year are you speaking to? And if you've got a 66 or 67, are the seats equipped to accept the headrests?
