A rearview mirror for a motor vehicle comprises an internal frame supporting a reflective element and a motorized tilt actuator assembly for adjusting the reflective element about perpendicular axes. The reflective element is attached to the internal frame through a pivot connection. The position of the pivot connection on the internal frame relative to the tilt actuator assembly can be selectively changed so that a single internal frame can be incorporated into mirrors of different sizes. Alternatively, the position of the tilt actuator assembly relative to the internal frame can be selectively changed.
