ONCE AGAIN... I have witnessed in wrecking yards AND owned several 73 and later A bodies with 9 inch front drum brakes, small upper ball joint control arms and small bolt pattern. Some contend that they dont exist. I say that if the factory didnt build the cars this way, then several cars that I have seen were DOWNgraded by someone afterwards. Why would so many people switch to SMALLER front brakes? Highly unlikely.
