Where is the collet sleeve/s for the Makita 3600 router?

[Antonio]

I spent a long time looking for these today - the collet adaptors that allow router bits with narrower shanks (1/2 & 1/4)  to be used - but could not find them anywhere.
I heard they are usually somewhere around the router table.
I wonder if anyone has seen this recently and know where it is before I waste money buying a new one....

Cheers,
Antonio
