Were headrests an option in ’68?

Our newly aquired 68 Barracuda convertible came with headrest buckets and I was wondering if thats an option for 68 or if they're 69 seats that came with the car? The seat cover pattern is a 68 pattern (LINK) as far as I can tell.

The hard part is we have a set of non headrest buckets (white) that are ready to go. If this was indeed an option in 68 would it be worth while to recover the headrest seats and use those?

Thanks
