97 Tahoe factory radio control knobs?

[DuckRig]

Just bought a 97 Tahoe and the factory radio station tuner control knob is missing. Looking for replacement knob and wondering if there is a spacer behind it. Does any one out there have idea or a damaged factory radio thrown in the corner. Would like to keep from putting in aftermarket radio.
