One very cool maneuver I’ve seen my husband use before when using a socket wrench set on his truck is to use a mirror to see hard to reach places.
For example, he was changing all of the plugs in the motor, and there was one he could barely reach; but he couldn’t see the thing at all.
So he gets an extension to put on the wrench and tries that. He still had no luck. He thought a few minutes then went and got my hand mirror out of the bathroom (thanks, honey) and had me hold it so he could see what he was doing.
And his wife was thoroughly impressed with those common sense brains of his!
