Regular wrenches and socket left me scratched, bruised and took nearly an hour to take the mirror off.
Ratcheting wrench like you have brought the time down to about half. A couple scratches.
The locking pivot heads.. 5 minutes and no scratches or bruises.
Here'* the thing.. it'* behind the window regulator (big metal panel) and access is limited, as well..the curvature of the door makes it a short swing for the normal ratcheting wrenches. The locking pivot allows you that extra bend you need to get more swing.
A quick tip.. being inside the door like that.. remember... the nut you are tightening is on a stud that is pressed into the plastic of the mirror assembly. Don't overtighten.
