For a Subaru WRX with a 6 speed manual transmission
Made specifically for models with reverse lockout
Thread size and pitch, 12mm x 1.25
I will also drill out the recessed area for the
trigger to go up inside the knob for reverse.
This may not be compatible with all years.
This is made from a brand new, real, regulation, billiard ball.
Ball is 2 1/4" in diameter.
  Threads directly onto your exisiting shifter.

This item is designed for 6 speed manual
transmissions only, with a stock shifter.
