So i have a question for the owners of the twm short shifter. Do you know the size of the threading for the knob? i want to get the shifter and a weighted knob, but i dont like any of their own knobs, so i want to buy a screw on myself. If anyone knows the diameter and thread that would be awesome! THANKS!!

 

You may want to ask TWM. They should tell you. I don't think they would have a problem with you switching knobs.
