Yeah! I'm screwed for the frame sliders ...
Didn't pay much for them so don't mind the cost; it's the fact that I've got a summer of racing with no sliders that bugs me.
As for the tail unit, you're not the first to ask. It was on the bike when I got it. It is in the Ducati catalogue, and recently I saw it here:

It says monsters 2000-2001, but mine's a '99 so that's flexible truth.
