This is a factory Hurst T handle shift knob from a 1971 Mustang. This is the actual knob that you hold when shifting that attaches to the shifter handle. This shifter knob is a real deal factory Ford installed piece. I believe this style knob was also used on a limited amount of GM cars from the factory like the GTO Judge. That said, this knob has 3/8 coarse threads and will fit multiple years and models of Ford/Mercury and even other makes of cars. Please confirm your specific application.
This factory Ford Hurst T handle shift knob is in good condition as shown. This knob has no pitting, major dings/dents, or other damage. The threads are in good condition. This is simply and awesome factory high performance Hurst shift knob.
