So now that you fixed the title, what axle are you working on?
Sounds like a 14FF to me.
Now I know that somewhere in the mid to late eighties, the 14FF apparently changed to one single nut with a key locking it to the spindle. A snap ring holds the key.
Lots of people like that style, and I would too if it wasn't for one side of my '95 axle. It wouldn't set properly with one of those. I went to the old style to get it where I wanted.
I have heard that a Stage 8 will work, but no experience.
