How to determine if 14 bolt is SF or FF?

[gmcjimmy88]

Is there a way to determione this without taking it apart? I have not looked at them closely yet but trying to get one now and would like to know. Thanks for all the help.

Under the hubcap/center of the wheel will be a hub sticking out if its a ff. If not its a sf.
