A mirror mount includes a mounting arm having a first end adjustably receiving a rearview mirror housing and an opposite end having an upper surface facing the vehicle roof when installed. The upper surface includes a plurality of upwardly extending projections generally aligned at the apices of a triangle for cooperating with spaced apertures in the sheet metal roof of a vehicle for locating a mounting arm to a vehicle roof. A bias spring and a fastener attach the mounting arm to the vehicle roof. In one embodiment of the invention, the opposite end of the mounting arm includes an opening having opposed facing edges and the bias spring comprises a spring plate having edges which snap-fit within the opposed edges of said mounting arm and provide a bias force between the upper surface of the opposite end of the mounting arm in the vehicle roof such that the projections are coupled to the roof under a compressive force which substantially prevents vibration and accurately aligns and holds the mounting arm to the vehicle roof. In another embodiment of the invention, the bias spring is a coil spring interposed between a lower surface of the opposite end of the mounting arm and receives a threaded fastener which extends into a snap-in clip for securing the assembly to the vehicle roof.
