That's true, David. BB was built One Piece At A Time.
But you won't know that unless you are really knowledgeable about Bullnose trucks. From the outside there's not much to see that doesn't fit - unless you know that an F250 shouldn't have a straight front axle, or even that the F350 didn't get one until '86. And at this point in time, under the hood it would take someone pretty au fait with Ford trucks to spot that it shouldn't have a 3G, it should have a starter relay, it shouldn't have a PDB, it should have a different A/C system, etc.
