Bearing for Ducabike Slave

[JPlip]

Hey guys.  Anyone know where I can get the bearing for a Ducabike Clutch Slave, the one needed for a 2000 M900 ie?  I have mine rigged with a brass spacer, and it works, but I want to do it the right way.  Looked high and low, and can't find a source for DB spare parts.  Thanks in advance!
