What are these front seats out of originally?

[GrandpaKevin]

Owner states they are out of a 71 'Cuda but I've never seen the adjustment lever in the front.

Any idea what these are out of?

Thanks.

I wonder if the seat tracks are from something else???

Judging by the seat backs, hinge covers and seat back release buttons they do look like '70 - '71 seats. The tracks with the arm in the front - well  .
