Ricardo,
They are Aero's and look at the front of the mirror where it mounts to the base, there should be a chromed nut with a hole in it. By inserting a small round something thru the hole you can unscrew it somewhat to allow an adjustment and then retighten it. You'll probably find that the mirror on the right side won't be able to be turned inward enough to allow a view of the right side of the car from the drivers seat. You may have to take a dremal and remove some of the metal on the base head to allow more inward movement. I've been told that all the mirrors sold are drivers side. That isn't true as I've seen them in Tweeks or another vendor that have both right and left mirrors. I've still got a little metal removal to do on mine before they more than a view of the side of the road! Why they mount the drivers side mirror on the passenger side escapes me, must have got a deal on the left mirrors.
