What should I do with this?

[fastsvo]

Hey guys,

My shift knob/shifter assembly has always been making a lot of noise and finally I got fed up with it and took it apart to see how this was installed in the first place.

The results....


Before I take it over to a machinist, what can I do here? It's currently held by set screws that are obviously not getting the job done.

In the interim I have replaced it with an SVO hurst shift handle and knob and what a difference in shift quality and feel.

Thanks,
Eric
