I'm 99% sure all HDis had 266mm discs for what it's worth (I've actually heard all the mid-late phase 3s had 266mm too). And I'm also pretty sure anything phase 2 onwards would have had ABS as standard, so it will either be that the discs are different sizes, or potentially (may be wrong) the callipers were different sizes depending on if you had lucas or bosch...
