If you are ever looking for discontinued parts for your curvy SV my best advice is to phone Suzuki UK direct, they will tell you if they have them in stock and also if any dealers still have a set in stock (most dealers tend to only order what they will use/sell and so do not hold stock of body panels).
You could also try
http://www.tcpsa.com/ for curvy accessories, they are the OEM accessories manufacturer, they might have a few left overs in stock.
