Nissan 300zx Z31 Kouki Shift Knob (adjustable) (71C / n/a threads)

This is a shifter designed to allow the user to add weights to the inside for a better feel or to act as a secrete compartment ( the cops will never think to look inside your shift knob, lol). The Z is designed after the kouki style of "Z" used for Z31's (1987-1989). There is an exact copy of this model designed with the zenki "Z" style as well. The stl is free to download for personal use only. Do not try to make money off my designs. suggestions and comments are welcomed and If you need a spec
