Used silver Lonza shift knob from my 180SX. It has a screw on nylon type fitting inside and should screw on to any factory S13-S15 shifter, including other Nissan’s with the same thread pitch and size.
The knob is about 2 inches high and when installed has a nice long drifter style feel to it.
I live in North Central Calgary and I’m willing to meet or ship at the buyer’s cost.
