i got a package for my '59 2-ton not long ago. it contained info for anything from half-ton, all the way up thru the various big cab/chassis options for busses, tandem axle stuff, etc. hope yours is as complete. let us know!
as for common, most of the cabs and everything in them in common on my '59, as well as alot of the drivetrain. frames, suspension, brakes, front end sheet metal, that's another story.
