Firestone Liquid out Post Problem

Brewing Processes
1

Bought a used Firestone ball lock keg.  Underneath the beer out post was what looked like what was originally two plastic washers or spacers, but the one appears to have the base of it broken off, and I now have three pieces for what I think was originally two parts.  I’m totally new to kegging and don’t know much yet.

If I order a new or used post, what typically comes with it?

Thanks in advance for your help.

I think you are seeing the remains of this

Thanks,

I’ll order one and see what I can do with it.
