The Big Boys don't have to settle for an AMP gauge that reads volts anymore - I now have dial overlays for the third gen Cougars.
These should be common with the Ranchero, Thunderbird, LTD2 and Montego of the same era.

And if anyone is interested I am also converting rectangular F-100 truck AMP meters to volts with a BAT dial.

Neither one is available on my site yet, so if you're interested send me an email.

Here's a picture of a converted Amp gauge installed in a '78 Cougar (thanks for the picture, PSquare).

These conversions are currently $30.00 when you supply the core.

And here's a picture of the 71-73 gauge with the optional VOLTS sticker applied. http://www.rccinnovations.com/Images/Volts/G3XV_2.jpg
