I got some made up by this ebay seller - Black border, MG logo on a red background on the LHS, £20 for the pair. Brilliant service, they look nice, and no quibbles at MoT time. Highly recommended.
Edit: Of course when I say "this ebay seller", it would really help if I actually included the pigging link! Try again dumbass...
