Nothing worked. Just order a new insert. Easiest way

 

Where can I order one or a whole new ARC shift knob?

 

Gotuning and evasivemotorsports can get them

 

Thank you I will contact them

 

Wait can they get just an insert?

 

I have brass inserts you could buy if you remove the plastic one already. Just need to make sure the knob has a 16x1.5 master thread with the insert removed which I believe it does.
A brass or any metal insert will be MUCH better than the plastic ones they use.

 

Sweet let me double check because I read somewhere arc was m18x1.5
