Tiny pin in steeing pot kit?

I'm replacing the steering box in my car and decided to also replace the
shoes and seal on the steering pot. In the kit came this little bitty pin,
where the heck does that go? I don't see it in the service manual etc.
Do you need it? Looks like it must retain something?

Does anyone ever replace the pin that holds the shoes? It looks
hardened and shows no wear.
