Whether 2 tooth or 7 tooth, the worm and sector are also different. You can use the shaft, throttle and timing levers and pitman arm but that's about it. Even the fittings on the bottom of the hand throttle lever is different. I've had a couple of good ones too, including one of those F100 ones. I finally had to just about give it away because nobody wanted it (including me).
Oh, and you can use the steering wheel nut!![]()
