I checked a photo of my assy and you ARE missing parts. The coil springs should connect to the turn signal cancelling thingies. Are your coil springs hanging loose?

These are 'L' shaped and pivot on the 2 posts to the right of each coil springs in your pic. On mine, it looks like a rivet holds these on - so I'm not sure how yours were removed.

It looks like your assy will function OK mechanically, but not automatically cancel. I've never run across these parts by themselves.
