Thanks, guys!
Dolph, watch out as not all pool ball shifter knobs are created equal. Make sure that the internal components are metal and not plastic and that it comes with a locking nut and is not just the screw on kind. You can use any that has the standard Mazda MX-5 shift knob threading.
So you bought the ball already drilled and with a threaded insert? I thought you might have drilled yourself a ball off a pool table.
