Plastic blinker assembly question

I need a piece that goes on the steering shaft and will fit behind steering wheel mount and not let the horn brass contact ride on it and not bend on the steering wheel mount

Well, I looked all over for that spare installation kit and don't see it anywhere.
They do sell them though, and that wheel does look like a Grant wheel.
