F100 The worm gear on an F100 is above the sector shaft when the box is mounted to the frame. Worm gear is below the sector shaft on an F-1. F-1 uses a nut to hold the pitman arm 53/56 F100 uses the pinch bolt. Top being F 1 bottom being F 100 with a chopped off steering shaft.
The box on the first post looks like a 57- 60 f100 pitman arm is from a 57-60 f100 box. I changed this post because I was talking about the 48-52 box posted above. Now that we are all screwed up I will go to bed. Sent from my iPad using H.A.M.B.
Yes the pitman is F-100, from 1957 and later with the tapered small end. The box is probably 53-56, because I think the mounting flange got bigger in 57, right? No F-1 (anything pre-53) parts there at all.
