Glider referenced awhile back a Nikko? starter clutch that works with some of the major Japanese make starters like Toyota & Nissan. Go to the Search tab near the top and type starter clutch or the Self Help Tips tab for Starter/Clutch tips.
Its a Nippondenso(Denso) starter a pretty common automotive starter.
Here a link for WAI Global... go to OE Bill of Materials and you can get the drive number and bearing numbers...or just take the starter to a local starter shop and they should be able to fix you up. WAI Global Part Details
I got one for my Heritage out of an 88 Toyota Pick up.
