thanks Bill..

does this mean that the 3spd was "on the tree" only? so am I correct in thinking that unless the truck has the original motor there is no way of knowing for sure what the original tranny was? if so how do you know if the truck has the original motor (are they numbered to match the vin as in later year cars)??
