Rx330

Does anybody know where to get an pair of side boards for the new 2004 RX300 (U.S. version RX330)? It is too high to ride on by kids and the grandparents. Does anyone agree to install a side mirror on the front passenger's side? My car crashed to a ramp when I was driving into a parking lot. The two doors on the passenger's side were damaged. The Japanese version Harrier got a factory installed side mirror at the front. It should be helpful. If you install a side mirror to your RX300, there won't be any different between a RX300 to Harrier. But a RX300 is much expensive than a Harrier.
