So your protrusions are still intact, ie there are places to hook the spring?

It's small and I think you have it. You called it the cancelling cam a couple of 
paragraphs above. It's just the little piece that moves toward the center so 
that the "blade" on the wheel can catch it.

I don't think being chewed up will hurt it, as long as it can still push against 
the little protruding nylon piece (cancelling cam.) It makes me wonder what 
caused it to get chewed up, however.
