Are these D27 auto locking hubs complete assemblies?
 

I just received these auto locking hubs for the D27 on my 86 Ranger. I am converting it back to auto locking hubs. It has been a while since I have messed with these. And when I did I was getting rid of them in favor for manual hubs. I want to make sure I have ALL the parts I need to make them work. Is everything here? I remember a woodruff (for a lack of a better word) key that slid into the notch on the spindle. Or was that only on the D35?

Another question, aren't the hub nuts for the auto lockers and manuals different?
