Stock 442 Rear Drum Size?

[stomis]

9-1/2 or 11inch rear drum? Rock auto has two options listed. Way more 9-1/2s than 11s but just figured I'd ask before I had to east return shipping...

Should be 9 1/2".

Should be 9 1/2".

x2, should also be the same for the A body cars as well (late 60's early 70's)

Correct. Only the 1973-77 A-body cars used 11" rear brakes.
