I made mine. Went to a bicycle shop and bought a thumb gear shifter and 6 feet of cable and hard tubing with a few connectors for about 15 bucks hooked the thumb shifter up to my stick and ran the cable down threw the shift boot under the body and back up the fire wall to the throttle body. Cheap simple install and tons of fun.works great when out side if my Jeep winching and I can set it at a higher rpm.
