JWest exclusive factory style replacement shift knob with threaded stud to screw onto RennShift stick.
930 4-Speed pattern for '75-'86 930.
Fits M8-1.25 threads on newest RennShift model. Please check the thread on your stick before ordering (older sticks were 3/8"-24). To check, an M8 bolt (typical 13mm wrench size) will be completely loose in the older 3/8" threaded hole.
Shim pack is included to clock the knob so that the shift pattern is aligned when the knob is fully tightened.
