http://www.ducati-shed.com/de/frame.html This chap is a great guy and a few of the DSC boys have gotten stuff from him. He adtertisaes on Ebay quite a bit and even though in Germany gets the stuff to you sharpish.
I guess this is the type of thing you're after which I have now bought the carbon version of from Ducati-Shed.
Failing that send a U2U to 'Dude' on this site as he can send you a CAD drawing for an ally item he made up himself.
Regards, Guido
