Nothing wrong with resurrecting my post from the past, I love talking about these gauges. Those were both my Clusters on Jolly's site then I sold one on ebay then it turns out to be one of our members. The gauges that are left to the ashtray I do have an illustration of one in a 1966 GMC owners manual for 4000 and up series. I'm going to have to dig it up this weekend when I get home. There should be a pic of one of these gauges on Jolly's site and it's a Voltmeter which I have. The idea of this smaller voltmeter mounted left of the ashtray allows you to have the two larger gauges like the clock and Tach and no need to run a Bat-O-Meter since all it is a voltmeter
