Just replaced my automatic gear shift knob with a carbon fiber and red knob from Black. I got the unit from the madness guys.
When taking off the stock knob, you must first pry off the chrome trim on the bottom. This exposes a very small flat pin in the front passenger side which can be removed by first sliding it with a small flat head screwdriver and then pulling it out with some pliers. The knob then lifts right off. Took some searching and figuring to find this pin.
The new knob installs with the typical set pin type setup. Doesn't adding carbon fiber to your car automatically make it faster?
Hope this helps anyone making the change.
