headrests for 66 or 67 abody or Bbody need just one

not sure if headrest were an option in 67//but that they were mandated in the latter half of 69// I do know a guy that has 69 seats with the headrests but I don't think He'll part with the headrests without the seats and they need a full go over
They were an option in 67 but very rare and they look different than the 68 and 69 ones but thanks for the tip
