I went looking for a spanner tool to tighten the little bezel nut on my wiper switch and heater fan switch on my Jeep CJ, and came across this web site.

Thought I'd share it with you all. It's not local, but it looks like they make a bunch of specialty spanner tools for different applications.
They also have an EBay store.
