I go that one better. I took a long cross wrench, cut the sockets off of the two ends 90 degrees from the one I need, and slid pieces of conduit over the two cut-off shanks. They slide in for storage and slide out for considerable added leverage when I need them. It works great. My bad back makes using even a long-shank cross wrench painful, but this does the trick.
NOTE: I’ve had enough experience with conduit to know that if it’s overstressed it’ll progressively bend rather than fail suddenly, so I’m confident that it’s safe.
I also have the usual stuff; a click-stop torque wrench with an impact socket, a breaker bar, a hydraulic jack, leather work gloves, a code reader, a $1 mirror to find the plug under the dash (), and a plastic garbage bag to put the snow-covered muddy flat tire in. I’m thinking of replacing the torque wrench with a torque-stick, just for space-saving.
For the record, I don’t recommend fix-a-flat. That stuff makes a mess, and a lot of shops won’t work on a wheel that’s been reinflated with that stuff. Although I realize that many performance cars now come with only that and no spare. Blah!
