My side view mirror on my pontiac grand am is broke, the only thing really keeping it on my car is the wire,I broke the screws in half that were holding it together, like I said the only thing keeping it on the car are the wires

how much do you think something like this would cost to get repaired at a bodyshop?? stupid ol me backed up and got too close to the fence and broke it off...

any suggestions to keeping it on my car in the meantime?? right now im using tape lol...doesn't hold too good..
