Bob,
Since the 55 pedal is two generations distant from your truck; it is rather a crap shoot to expect the pedal hinge bracket, throttle socket location, and toeboard bushing on your truck will line up. The bushing on the toeboard is not very forgiving relative to differences in up/down/left/right position. Perhaps someone can get you some measurements from a 55 pedal? The throttle linkage length is different on splash oiler engines vs insert bearing engines as the pivot on the engines changed locations. I grafted a 1958 engine throttle shaft to a 1942 pedal (socket type) with some angle modifications, no change in distance but it was an adjustable linkage apparently used on large trucks in 1958. It may be more simplistic and relatively original to extend/modify your present shaft to fit your 1946 pedal. There is a solution, you just need to find it!
