Managed to find a set of 1968 bucket seats with the optional head rests.. Came out of a 1968 Buick skylark. I thought they were 69-72 center release, until I saw the side releases. Then found the buildsheet to prove option A81- optional 1968. Pretty excited about these! Will be pearl white covers.plastics going into my 68 red on white convertible. Really like this one! As do the girlfriends daughters = this one can stay!
