Part number 3577529 440-6 kickdown rod

[71Shaker]

I'm looking for some confirmation of a part that I received many years ago. I am posting pictures but want to verify it is a 1971 440-6 trans kickdown linkage rod. There is a part number tag on the piece and it has been kicked around many shelves but since the tag is not attached I would like to validate it is the correct part. In examining the ends I don't see any evidence of installation. If this is correct, I see one NOS sold last year but would like any input as to the value.
Thanks in advance!

Any thoughts from the folks on this website?
Thanks in advance for anyone's thoughts

What makes you think this is a 6-pak linkage and not a 318?

Two things
1. Part number on the tag
2. Picture from another member showing an NOS 440-6 kickdown linkage.

Why do you believe this is not a 440-6 linkage?

Isn't there apart number on it like this?

Thanks for the picture. I checked my part and there is not a part number on it. If anyone has a kickdown rod with part number 3577529 would you be so kind to post it?
Thanks again
