I had a few guards spare that had seen better days. I straightened them out as best I could, bead blasted them to get rid of old paint and rust, and sprayed them in silver metallic.
They include a new stainless steel bolt/washer set as shown in the pic and are £12 each plus p&p. New ones are over £57
Not the best but better than burning your riding trousers on the exhaust if you haven't got a guard fitted
