11" to 12" rotor swap

That list is just what RockAuto shows under "applications" for an 11.75" rotor, not really sure if its all inclusive or not. My guess would be that there are some discrepancies. Some M bodies did have the 11.75" brakes, but I don't personally know of any applications after '81. An '88 Gran Fury uses a 10.97" disk, in fact the same one listed for a '73-'76 a body, same goes for a Chrysler 5th Ave. So, according to the part #'s at Rock Auto some of the '88 cars COULD donate rotors, but I don't think any of them had 11.75" rotors.
