Most parts store employees around me are idiots.

You know what is hard to find in the US, adjustable metric wrenches. Lots of imperial/english but no metric versions. When will the US see the brilliance of metric!?

I lost the adjustable metric one I brought from the UK but I was able to file the "/" off a Craftsman adjustable English one and it works pretty good.

LOL Just for kicks, Google had 1.4M hits -- made me think of the old commercial, "...a silly millimeter longer..." NM
Note they come in sets too!!!

I thought you needed an adjustable metric wrench to install a Johnson rod?

... Google had 1.4M hits ...

I love it! And one of the hits had a "... 8'' Metric Adjustable Wrench". Close, but I was looking for a full metric adjustable metric wrench. None of that mixed imperial/metric.

It's hard enough to find a metric adjustable wrench, but Whitworth adjustable wrenches are just about unobtainable nowadays, except from some boutique UK suppliers catering to the vintage motorcycle crowd.

You are looking for the wrong thing. You need a Whitworth adjustable spanner.
