Heater control part
 

Has anyone ever seen this part?

It mounts just above this part inside the automatic heater control between the seats of an 1980's 911. (in my case, 1983 911 turbo)

Can you get this piece, or is it a matter of replacing the entire unit?

I would like to buy just the piece.

Thanks for looking. Any and all comments appreciated.
