These Pontiac power & volume knobs are such junk!
The interior part that pushes on to the metal volume shaft is that brittle clear plastic GM loves to use on things.
And, the **** is of course long since discontinued!
I might try filling the hollow parts of the **** with epoxy to reinforce the **** better.
