I have a question to add to this discussion.  We've talked before about 
switching this system from amperage to voltage.  And there is a good 
tech article about the swap.  One thing that is not addressed clearly is 
the gauge.  I'm guessing that it's necessary to use a replacement gauge. 
 On my '63 I think that would be a fairly simple swap as the small 
gauges seem to be the same size as modern replacement gauges.  However, 
if a guy wanted to keep his original gauge, I'm wondering it it would be 
possible to retro fit the faceplate and needle onto a modern gauge or 
somehow change to guts to convert it to a gauge that reads voltage 
instead of amperage?  Has anyone tried this?
