'76 Charger steering column help

I think that this is the correct order.
And then the metal ring gets pushed down and holds everything in place.
The round plastic piece with the brass? ring on the back is partially broken. I don't know what it's called, or what it even does.
The turn signal lever is hanging because my turn signal cancelling cam is broken, and the pot metal piece that is in it and the lever screws on to, was broken. And now I can't find it.
