If the "receiver" -for lack of a better word-in the mirror housing isn't
damaged, you should be able to pop a new replacement right back in. Look at
the back of the plastic on the mirror, should be something in the center,
and a corresponding mating part inside the mirror housing.
The receiver seems to be fine and the plastic on the back has a "lug" which
looks as though it slips into something on this receiver. It doesn't look
broken but not being an expert it's difficult to tell. I'll check with Ford
in the morning.
