The conversion was done on a '72 B body rally cluster, they unriveted the faceplate on the factory ammeter and installed it on a Sunpro CP7985 voltmeter. Worked pretty slick on that gauge but might not work so well on others.


a worthwhile article but could be summarised as "find a voltmeter that will fit where the guts of your ammeter currently are" - the value was in the info as to which one they found for the B-Body in question.

If anyone has found a specific voltmeter for other bodystyles, please post away (E-Body standard for me please )
