I have those on my Raider. They were original on an import to Australia. They are a pain to install and adjust. The up/down is done by bending the mounting tube. Every time you bend the tube you have to bend the top mounting clip. But..... many hours later I have good rear view mirrors. I do find that they block my vision forward to the left - have to be careful.
