Speaking of a-body cars here;
Beginning in 1973 all v-8 cars (a-bodies) had big bolt pattern (4 1/2") and disc brakes.
However discs were an option on '73-up /6 cars. If a /6 car had discs they were also big bolt pattern. However I've seen many '73-up /6 cars that still had drum brakes with small bolt pattern (4") wheels. I've never seen a '73-up /6 a-body with big bolt pattern and drum brakes.
Hope this helps,
Dallas
