The California mirror may not have enough adjustablility out of the box to allow you to see properly. However, it is a very simple job to remove the mirror from the housing (two screws secure it from the underside). Then it's very easy to enlarge the opening that the mirror boss passes through, which will afford much more freedom of movement. It may be an iterative process (remove from car, dismantle, remove material, assemble, install on car, :furious:, remove from car, dismantle, remove material, assemble, install on car, :furious: again...) but once you've got it right, you'll be very happy with them.
