Not absoluteley certain, but I think the Charger shares front end components
with a C body car.
I seem to recall the upper and lower ball joints being the same.
(this was back in the 80s)
I changed from factory discs on a 67 Chrysler (4 piston Budd) to discs from a 73 Plymouth Fury.-----Direct bolt in with no modifications.
(the 67 Rotors had been discontinued by '83, and the "Disc Brake" lower ball joints were over $100 each way back then-----swapped to 73 "C" body brakes for about $80 at the time.)
Later --rebuilding a 71 Charger front end, I realized it used the same parts as the 73 Fury.
