The snowplow came by with snow and ice flying, and broke the driver side power mirror on my 1998 Camry. The housing and mirror glass is fine, and the power device that turns the mirror is ok. What broke is the plastic piece that attaches the mirror to the power motor. This piece is square, has a round hole in the middle and has two little plastic screw like devices that go into where the motors turn. All I need is this plastic piece. Does anyone know if I can buy just this piece, or do I have to go for a whole new mirror?
