Removing Old Freehub Body I saw this.  However, looking at a old 7 speed freehub body, it looks like it takes a special spline wrench (TL-FH10).  It looks very similar to the fixing bolt here.  Or do I need some other wrench to remove it using the notch?  I also did see this.

Do I need this special tool to remove this freehub body or am I totally off?  Is there some other way to remove it without destroying it?

UPDATE: The freehub body does not have notches on it.  I will post a picture of it.
Just a 10mm allen wrench was needed.  Looking at the head for the bolt, it looks special, but its not, so I was deceived.  Probably not a traditional bolt head, as the axle must fit through it.
