steering column turn single exploded view

the turn signal in my 72 demon isnt disengaged when i turn the corner.. i tool it apart and the cam looks good not broken.. what is it that trips the cancel cam to turn the blinkers off?
here are a few pictures you can see that cam is good. the other part is that what trips the cam.. if so y isnt mine tripping it

Underside of the OEM steering wheel has a heavy steel ring with one end turned down about 1/2 inch. That is the finger that bumps the cancel cam. I don't recognize the part held in the second pic

you have a picture of that steel ring and where i can get one. the second pic is the back side of what the steering wheel attaches to

There are actually 2 pieces. The ring sits on top of a fancy hard plastic isolator. I think maybe it prevents the finger from providing a ground path thus blowing the horn? I forget. This is all typical/general info. A TUFF wheel or other sport wheel might be different. Showing both sides of your wheel might help
