This is made from a brand new, real, regulation, licenced billiard ball. 
Thread size and pitch, 12mm x 1.25
I will also drill out the recessed area to allow the trigger to go up into the knob for reverse.
Ball is 2 1/4" in diameter.
  Threads directly onto your exisiting shifter.  Comes with a jam nut to lock it in place and ensures that the knob will not vibrate loose or fall off.


This item is designed for manual transmissions only, with a stock shifter and reverse lockout.
