I have a pair of Lyotard 36F pedals (see here for an image: http://slowbicycles.com/2010/06/16/lyotard-pedals/ )

One of the dust caps is missing. It is the threaded type. The prices for the replacement caps on eBay are frankly insane. Are there any other brands of pedal dust caps that are interchangeable with the Lyotard pedals? Will MKS dust caps work?

Thanks!
