Herman Miller Fully Adjustable Base For An Eames Fiberglass Shell Chair

Well all it needs to be compete the bushing that goes down inside the base that keeps everything from wobbling around. Sometimes they are brass, sometimes they are some sort of plastic looks to be the same thing the glides are made out of . Well and of course jt needs a shell to sit in as well.
Hopefully someone can put this to good use..
Thanks for looking.
