I searched, I searched! I couldn't figure out exactly what type of gauges I need. I know I need 5" for the speedo and tach and 2 5/8" for the cluster, and I am leaning towards either Pro-comp or Ultra-lite, but I don't know if I need mechanical, liquid-filled mechanical, electric short sweep or electric full sweep for which gauges. I'll be running an L28ET in my '73 240Z. I want fuel level, oil pressure, water temp, oil temp, voltage, and boost, and maybe fuel pressure in addition to the tach and speedo
