Some years back I remember year specific assembly manuals for Task Force, they came and went, then all that was available is the one titled 55 to 59, which is untrue. Like you say all dates are 54 and 55 on the drawings in the manual. Its better than no assembly manual, and basic sheet metal is pretty much the same through out the years. Exceptions are beds, gas pedal attachement, some holes in fire wall, hood hinges etc. And I suppose wiring as well.
