To remove the clutch and alternator rotor, according to Haynes, special Honda service tools are required. Where would be the best place to get these? Thanks.

is that not just a clutch holding tool which gives you something push against while you undo the nuts? you can get them from halfords for about £15 or if you have any small flat bar abou that you can bend, you can make them easy enough.

According to the Haynes manual, you need to hold the clutch, as well as use a little Honda thing to remove the center. It also clearly states not to use anything other than the Honda tool for removing the alternator rotor..
