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?
