Brake Changes on A Bodies

You could fill a book with what was available at different times, and differences between "same size" brakes in different years...
Basically, 9" drums on slant cars, 10"drums on V8s, discs optional on all... and different versions of discs and bolt patterns on '73 and later. And I know there's exceptions and variables...
Heck, I've got an 8.25 I yanked out of a '74 Dart Sport that has factory 11" drums- never officially available, but there were times the assembly line just used what they had in order to keep things rollin'...
