for sale, I have a Mazda 3 weighted shift knob that I used on my pro5. I bought this shift knob brand new a couple months ago and barely used it, so it is still brand new.. This knob is a lot heavier then a stock pro5 shift knob and in my own opinion makes shifting smoother... So if anyone is looking to upgrade their shift knob, I am selling this beauty $60.00 shipped to your door... Let me know?? Thanks... Chris.
