Where to find a film advance lever collar for a Nikon FG that I am restoring?

I am in the process of restoring an old Nikon FG. I have gotten it mostly working, however, the film advance lever is missing the collar to hold the film advance lever down. The lever works smoothly, but if you hold the camera at an angle, the lever will slip out of the place it should be.
I have attached a photo (not mine, but same camera) of the part I am looking for.

A scrap camera on Ebay is probably your best bet, This one is a close relative of yours.
