$875 1966-67 barracuda bucket seats, backs and tracks (unknown year)

Glad you found that out. Might have save some heartburn selling them to someone only to find out they won't fit. Hey this hobby is a learning curve. At 64 I'm always learning something new about Ma Mopar.
Me too! like to make sure I get as much right as possible. Now even measuring the 69 buckets I question if they are right or just taken off something else. Over the course of 50 years all sorts of things can happen. Thanks for pointing that out in either case. Now I am trying to figure out what the bracket are out of 1964-1965 barracuda would be my next thought - they bolt up to the tracks on the 66/67 seats (tracks still on seats with angled slots for double the adjustment- I believe was factory to give even more seat adjust ability. The 69 seats do not have this feature but I have friend that told me his 69 seats do have this feature.

Almost get more confused the more information I get as seems to be different more than consistent.
