My ‘75 Z has an ammeter in the dash, but no voltmeter. I don’t think it’s very useful to only know the current draw, or maybe I’m just more comfortable with voltmeters in the dash. Anyway, I’m probably going to replace it with a voltmeter from a 77-78 Z. But that backwards speedo is intriguing. Start out at 180 mph and slow down from there. Better have good brakes!
