I have a chap who does body work and you really do need to change the wings. He buys wings from Charles Trent online who will have a big stock of wings. You maybe lucky and get the correct colour but if you get a genuine used one in a different colour at least it will fit not like the NAUGHTY WORD-NAUGHTY WORD-NAUGHTY WORD-NAUGHTY WORD- copies.

Also email Global parts in London they have sold me loads of bits for my Beemers over the years. Great prices too!
