Subject: [CR]Help removing 1st generation Dura Ace freehub.

Hi all. This is an early DA cassette hub where the small cog threads on to lock the the other slide-on cogs in place. Once you remove the axle there's
   an 8 splined female bolt head instead of the later 10mm allen head. Is the re a tool made for unthreading this? Or something I can use for this purpos e? Does it, in fact, unthread?¬†And can I then thread on a later freehu b unit to the old hub shell? Any info would be appreciated on or off list. Thanks. Billy Ketchum; Chicago, IL; USA.
