I've been down this road with the fairings on my 916 alittle over a year ago where the dzus fasteners came out, well I believe they did and the whole bottom have torn off. I replaced mine with some from a guy in china, ebay id is (wing576) and he is spot on. There is a thread on Ducatisti forum that I did with the story about how mine came off.
http://www.ducatisti.co.uk/forum/duc...8-916-bip.html well worth a read as the guy from china copied my old fairings just by me sending pictures via email.
I did have some changes made as well and they came within 2 weeks.
