70-72 Chevelle 454/365 original cowl air cleaner

[69gmmuscleluver]

Need help please. I've got an original unrestored cowl induction air cleaner that I'm quiet sure came off a 71 454 car. The only thing thats throwing me off is a green stamped date on the inside(air filter area)that's dated 8/9/70. I'm going to sell the unit and want to confirm that as far as the decal goes is it 71 only? I'm aware that actual fit/function I think will work on 70-72 cowl induction cars but due to the survivor shape I think it's worth more for the correct application. Any idea what a fair price would be? Thanks in advance.
