So I woke up today went to my car an noticed that somebody had ripped my passenger side mirror off. The mirror housing is still on the car with no damage to the housing. Wires inside for the motor and defrost are not cut and the motor still works. My question is that I went onto an lexus oem parts website and seen the whole assembly they sell the mirror separate from the housing. If I buy just the mirror how would it be put back into it's place? Or would I need to buy the complete housing with the mirror??

Any info would be great thanks.
