Have a '90 K5. Obviously no tach, but I'd like to have one especially when I'm towing. I don't really care for the "under dash" clusters and it doesn't seem there is a "pillar mount" gauge pod that really works for our trucks. So, I thought I could get a small one and mount in the ash tray. Digital would be easier to read and I could just open it up to read it and then close it when I don't need it. All I can find are needle gauges. Anyone know where to find a small digital tach? Also, while looking I did run across some "universal" pillar mount pods from JC Whitney. Has anyone tried them?
