New, Unused Adapter Compression This is a genuine resin part for replacing the genuine AT shift knob on a Fairlady Z (Z33 late model). When installing on a Fairlady Z (Z33 early model), you can install it simply by replacing the white resin cap with a blue resin cap. Please replace the shift knob at your own risk. Please judge the other details from the images and purchase with your understanding. I have multiple units in stock.
