Bucket seat identification

[spoolinhard]

These were laying inside a charger I just bought. I'm guessing a or e body, maybe even later b body? Seat tracks are there. What are they out of, and what is a realistic value?
Thanks

They are NOT a 71-72 B-body... Possibly pre 71 or an ebody?

They are not 70/1 e body. That makes me think 72-4 e or a body
