It can be done on 1999 shifters and later(not 1998 or previous). You need the
shift disc, EC-RE-061 and the front toothed bushing, EC-RE-062.

The front toothed bushing is not absolutely necessary. It is an
inexpensive part but replacing it makes doing the conversion more
difficult. The spring that covers the through bolt is tricky to
reattach. If you don't replace the front bushing, the cable pull
between clicks will be the same. The distance you have to move the
lever to get a click will be longer at some point.
