Need help identifying seats

I’ll get a pic of the back and side when I get back in town from work. I am pretty sure the foam was purchased for a 71 a body, I’ll confirm that too. I went on legendary’s website and the pic they show for the foam looks like what I have. If the seats are correct, not sure why the foam is so off.
The reason I ask, is the 70 bucket had 2 pot metal hinge covers per seat, plus the seat back. 71 and up the seat back/hinge covers is all one piece. This will help us narrow it down to year.
