RCCI gauge installed in the panel
This is the gauge installed. As you can see, the new needle has been beautifully repainted, and doesn't match the old faded gauges. I'll fix that next time I have the instrument panel out.
I've written this up over at the blog at wyowanderer.com/adding-a-voltmeter-to-the-ford/
I've uploaded a video over at Youtube at youtu.be/U7LD3AXA98s that describes what the install actually accomplishes.
