67 buckets - what years will interchange

[dsd1967]

I just picked up a set of 67 A body buckets with tracks and am trying to figure out what years these will interchange with. I know the seat backs are different than a 68 or 69, and I know the 69 had headrests provisions, but were the basic frames and tracks the same?

If those buckets have the headrests they are probably worth a lot. Had my 67 buckets
redone - at the time I could find the pieces that go in the seat for the headrests but
NOBODY had the headrests. 67 headrests are different looking than 68 and 69 and are
a different width -- can't put the 68/69s in the 67 buckets.

So at best, they are 67 to 68 if you don't want headrests.

These do not have headrests....I'm not that lucky to find something that valuable.
