Since we are on the subject of mirrors, on the 2004 - 2008 Ford F-150 (and I think the earlier models too), the sail panels on the door the mirror attaches to is flat. I have noticed the sail panels on the new 2009 F-150's have a bulge in the surface about a quarter inch in depth.

I'll bet this was done for better aerodynamics. Ford spent alot of wind tunnel time on the new 2009 F-150 and they must have found that a little curving of the sail panels by the mirrors is better than just a flat surfaced sail panel.

This would be an easy modification for any side view mirror with a sail panel, it will just take, you guessed it, a little bondo.
