I have the whole stock clutch from an 1198.
In the 1198 I'm using now the slipper clutch I had in my 999 and the only thing I had to replace was a washer and the nut but everything else was the same.
I'm not looking at separating the drum from the rest, but I'm selling the whole setup for $50 + shipping. If you'd like call me at 760 576 4073 and we can compare measurements.
