Here is a gear stick that lets you drive like a real ninja. This Samurai Sword Gear Shifter should fit most automatic transmission cars. It has Japanese braided pattern to make your car look cooler. The handle measures 26cm.
This Katana shift knob is pretty easy to install. Simply remove the original knob, install the sword, press it down to fit the sleeve, and tighten the screws. You can order these in shorter versions too.
