you will find that a lot of times working on these old trucks that you are going to have to do a lot of the thinking on your own. Take notes, pictures, whatever. I'm hoping the reason you are asking isn't because you have torn it apart and don't remember how it went together. These things (the trucks in general) are 50-60 years old, and utilized a lot of antiquated, and at least to our modern way of thinking, bizarre engineering designs. A lot of the information has been preserved, but a lot of it is in the heads of an older generation. That is where this forum comes in handy, but even then sometimes you are just going to have to bite the bullet. We have been experiencing this at work lately, the manuals don't have any relative information. I've had to draw my own breakdowns that represent what we actually have. (I work for a public utility, and they just cannot seem to order a STANDARD item, they almost invariably "SPECIAL ORDER" some bizarre component that isn't listed in the standard breakdown.) Either way, you will figure it out eventually. But if CarbKing doesn't have the answer, it is pretty safe to say it doesn't exist. Good luck.
