its not 9" or 11" its 9" or 10" that I know of and the 9" usualy have what look like heat fins on them.
Like this but I have seen some 10" with the fins also
only way to be sure is measure them inside from side to side.
You should even with new drums have them turned to get them 100% true but every auto store tells you its not needed to get you out the door.
