I decided to detach the Civic mirror and see if I could repair it (or temporarily hold it together with Gorilla Tape). I detached the 3 8mm nuts, dropped one inside the door, and saw that the broken part is perpendicular to the portion that bolts to the door.

I am positive that I have a spare mirror somewhere, but I should be able to bolt a mending plate, too.

I would rather repair the plastic itself, but I cannot imagine that it would hold.

I thought that heat staples would do the job, but I finally looked into them.

Somehow I visualized normal staples that you heat up and drive into the plastic, but they go backward, none of them are straight, and you bury the head in the plastic.

They seem great, but they don't seem to make anything rigid.

I am trying to keep my mirror from flapping around!

I have that piece of aluminum plate left over from acid-washing my Accord catalytic converter, so maybe I can drill holes in that that line up best with the strongest parts of the plastic.

I need to put some Gorilla tape over the hole.
