I checked out my local Coldwater Electric Motor True Value here in town as they have a lot of hard to find stuff. They had a 19mm hex wrench plus I took the advice here and made a 19mm out of a old 5/8 spark plug wrench that had a 3/4" hex head. It was just a few thousands oversize so I sanded it a bit and stuck short a 3/8" extension in the opposite end. It fits good, so I now have the best of both worlds. They didn't give that hex wrench away at $15 a pop. I may consider taking it back.
Ready to remove that front tire in the spring.
