I don't think you will find anything that will simply bolt up. You will have to do some drilling, cutting, etc.
Check out the fenders in this EMGO catalog:

Of course the local motorcycle recycler would be my first stop, if your town has one nearby.
Good luck & please let us know what you end up with.
