Repair (see this pic:

Start with any donor mirror of the same side and with the good parts that are broken on the desirable mirror. The broken one here is a rare '96 Bronco power signal mirror, and the donor is a common (cheap) manual mirror with a black front trim.
Both mirrors must be dismounted before any inside parts can be swapped, but it might be easier to remove the mirror glass while the mirror assembly is still attached to a door since that's the best way to hold it. This one was already broken, so it didn't matter.
Note the 8-position connector on the upper mirror, indicating it's a '96 signal mirror. All other power mirrors have a much smaller 4-pin connector.
