All shift knobs are custom made. Our shifters are predrilled with a 16 mm insert. This shift knob is 2 1/8″ in diameter and designed to look just like a cue ball. The design is on the opposite side of the insert. We also have adapter kits available to fit almost any size shifter if needed, click here to see Standard and Metric kits.
