Utter nonsense. Once the tooling had been changed and the inventory of 20-louver hoods was exhausted in the U.S., every '32, four or V8, was equipped the 25-louver hood. As that process took place, if there was a destination preference while the old hood inventory was being used up, it would have been to southern destinations nationwide, not west versus east. The relative rarity of 25-louver hoods is a function of the timing of the change, which took place very late in the U.S. '32 model year, not otherwise.
