Valjoux 72 servicing. Stud left over?

[texaspledge]

Ok feeling a little silly. Just finishing cleaning and rebuilding the base movement of a valjoux 72. Here's a pic of the keyless works.

Seems to be great so far but wait I still have one part in my tray. A stud of some kind. Anyone know where this goes?

Thanks!

Nevermind, found out it was a dial foot key...
