Ken,
With the introduction of the the new commercial bodies in July 1930, a new 'AA' radiator and shell combination was used.The shell is distinctive as the top of the front opening (just below the Ford emblem) is a straight line from side to side, while the 'A' commercial shell is the same as the passenger car shell except for being black painted steel.
The truck radiator has four rows of oval tubes instead of three rows like the car.The corresponding radiator tanks are also deeper.An 'A' shell cannot be installed on a truck radiator and a truck shell will have a large gap between the front of the radiator and the shell if installed on an 'A' radiator.I'm not sure but it may not reach far enough rearward as well.
The remaining sheet metal (Cab, hood, fenders) on these trucks were the same as that used on the 'A', so no hood shelves were used.With everything properly fitted the bottom sides of the radiator shell should have approximately 1/32" clearance from the fenders over the frame rail, and the hood sides should have approximately 1/2" gap at the bottom.
