For future information I figured I'd add this. If I remember correctly, the 1937 through 1948 passenger & light commercial (pickup) used the same steering gear. The roller sector came out in 1937. They were cross steer set ups so they had the pitman arm on the bottom rotating from right to left. The drag link crossed over to the other side to steer the right spindle with the tie rod between the two spindle arms. This wouldn't be easy to set up on a model A. The F1 box used from 1948 though 1952 is a side steer set up but it's set up different from the early Ford types that used side steer in that the worm gear & steering shaft sets under the sector instead of on top of the sector. This changes the angle of the steering column plus the box has to be modified to fit in the frame like an A steering box does. In 1953, Ford changed the steering box for the F100 to put the worm gear and shaft back up on top but retained the side steer design. This is why the F100 box from 1953 through 1956 is preferred.
