Hi Guys. A good source of information about this is the Sheldon Brown web site. As I recall, Sheldon wrote that you do need a special tool to remo ve the old freehud, (and he pictures one with the tool #) and that at lea st the seven speed hyperglide freehud could than be attached to the old bod y. I have been meaning to try this, but haven't gotten to it yet. Go to, click on Dura Ace, it you should have all the inform ation you need. Good Luck.

Bye the way, would you please write and tell us if this worked. Thanks

Merry Christmass. Tom Harriman. San Francisco, Ca.
