What year are these front seats?

[aquifer]

Can anyone tell me what year these front seats are? The car is a 67, but I don't think the front seats are original. I think they are from a 64. There is a knob near the lower hinge that you can turn to adjust the seat back angle, but there is no locking lever of any kind for the seat back - they just fold forward.

Hopefully this picture shows enough detail for an ID. Thanks!

Front & rear NOS or used OEM door panels for a '67 in the original Gazelle color (dark tan/light brown).
Also looking for used white headliner pieces, both perforated and non-perforated.

Yeah I was going to say 63 frames with the later material covers. Let's see what some of the others say.

Weird angle, but yes, they look like 62-64 seat frames painted black to me…
