I think there is a pair of wings for sale in the 'for sale' section. you will pay a fortune for them though as they are the last ones available.
As regards to blanking them off you could do this as your car doesnt NEED side repeaters.. depends how well its done though.. it could look gash!
you might be better getting a decent set of pattern wings as they are cheap as cheap and are normally a good fit. just depends on how 'original' you want the car to be!
