I've had good luck with the chat and email when communicating with Ducati Omaha.
I was missing a part from mine, the square grommet the shock wire route through, and the dealership, I forget the name but they were on the east coast, didn't have a problem finding it. Some part numbers are in the back of the later revisions of the install manual. This is from a PDF that's circulating, but a dealer should have access to the newest version.
