Bifold door bottom pivot point

A home owner from Lincoln, Arkansas says:
Hello - I have a bifold door purchased in the early 80's. The bottom pivot pin has gotten lost and I can't find a replacement. It isn't the little pivot pin, this one is about 1/2 to 3/4 in diameter.

Unfortunately, neither the door, nor the part have names/numbers.

Do you recognize it and might have a replacement?

Thank you for any info you can provide.

Your pin looks like the inside portion of our 23-119 or 23-135. Check them out and see what you think.
A home owner from Lincoln, Arkansas says:
Oops, the picture names didn't carry through. I need the one on the left, shown in the bottom of the door, not the one on the right that I held in my fingers.

The 2 links you sent are the one in my fingers and they don't work. The one I need is larger and only has 6 fins.

Aside from the fins, how else do they differ? Could I maybe see a picture of the one you need removed?
