If you go on ebay and buy a
Subaru WRX shift knob, preferable the round ball shape, they are EXACTLY the same AND you can pick many different colors. I had a red ball shifter when I had mine installed and had my red car. They just screw on with a bolt/nut on the inside. Fits the JPM exactly without any mods. They start at around $30.00 but I have seen them even cheaper.
Here was my first shift knob. It color matched the red in my car but the red leather got dirty really fast from my hands when shifting so I swapped it out. This one came with adapters and still worked with the JPM short shifter. I would still recommend buying the WRX round "gumball" version.
