BTW, if you already have a driver's side mirror that works and you're thinking about purchasing a matching passenger's side mirror. here's a test that might prove useful...
sit in the passenger's side and look over to the driver's side mirror (adjust it of course) and see if you can see the left rear fender. if you can, then a matching passenger's side mirror should work well from the driver's side. the geometries involved are (no pun intended) mirror images of one another.
i couldn't find one that did though, so i bought a stick on convex mirror and stuck in on the driver's side mirror (temporarily) and ran my test again, and i COULD see the left rear fender from the passenger's side! so i was set.
and then bought a matching passenger's side mirror to my driver's side mirror and drilled two holes in the passenger door like those in the driver's door and a stuck the 4" convex mirror on top of the 4" matching passenger's side mirror. and voila! i can drive on four lane roads in the left hand lane and not be afraid of changing lanes if and when someone passes me on the right.
