Yours is a common request due to the replacement cost of one being a disporportionate percentage of a typical 1200's value. Ebay seems to be the usual source for OEM and reproduction ones. Painting to match isn't cheap either if you want dead on Honda colours.
A similar Made in China piece of plastic in the form of a candy dish would retail for a buck or two. Be prepared for a hundred times that.
Aside from that bad news, welcome to the forum. If you put your location inyour profile someone might be able to steer you to a source in your area.
