Sarching for 96007600B returns a few results, one of which is this document:
http://www.parimoto.de/downloads/pre...sories2005.pdf Although it's in German it indicates that 96007600B fits M620, 750ie, 800ie, 900is and 1000ie for years after and including 2002.
This document also says the same thing:
http://www.ducati-czech.cz/katalogy/...51 dff6ab7aa8 Part 96007600B are for aluminium oval cans (Page 18 in the above PDF document). Looking at the relevant picture they also seem to be standard rather than high level cans.
You should be able to get slipons from a number of different suppliers for you 1000ss. The same end can parts for both 750ss and 900ss, in the newer ie shape (1999 onwards) are interchangable.
I have a set of SIL MOTO cans on my 2002 900ss, which also fitted on my pervious 1999 750ss.
