To be fair, allowing the Ford 9" was a cost saving measure mostly aimed at allowing A Sedan cars a way into CMC without having to spend big money converting their cars back. It had no realistic effect on those building a CMC car because no one would be dumb enough to add the expense, drag, and weight of a 9" when the stock rear ends were bullet proof on cars with 230 HP, 16" rock hard tires, and 12" brakes...
