As requested...
Here are a couple pictures of the current setup. These just clip onto the visor. I originally had the passengers side one on the passengers side visor, but the viewing angle was pretty lousy, so it winds up on the drivers side. Although you can't see in these pictures because I am in the driveway, but they do a pretty good job of filling in the blind spots.
Drivers side. You can see the DS mirror deflector I made from an old campaign sign. The interior mirror works pretty well, but it's not adjustable, and it reflects the sun into my eyes if it's anywhere behind me. The new mirrors do a pretty good job of filling in the blind spots.
Passengers side. The PS exterior mirror is still waiting for a mirror deflector to match the DS. I am going to remove the junky mirror on the inside of the PS door, since it basically does nothing useful even in its best position. I think this is about the right position for the new mirror.
