Replacement throttle knob

[jsz]

I have a 2002 21V and the throttle knob has been loose for years. I’ve seen other similar posts on how to tighten the knob or fix the taps button but what I am wondering is if anyone knows where to find the original knob. I called tige and they gave me the manufacturer but the manufacturer does not make that knob anymore. Only a generic knob without a taps button. I am wondering if anyone here knows where I can find a used original knob like the one pictured

Did you tighten the hex screw in the knob?

Yes, but the base of my knob is cracked. Probably due to overtightening… And over 1000 hours of use.
