Well after collecting gauge pieces for 3 years, I finnally built up the gauge panel to use in my K5 Project. The special gauges are the 0-100 Oil Pressure (most are 0-60), the Dual inlet AIR gauge indicator (for regulated and tank pressures of the On-Board-Air system, of course!)(there's 2 pointers in that gauge, one orange one white), and the 5000rpm Tach w/integrated Fuel. Also is the 90-91 speedo with trip and elec sensor box hanging off the back (In case I need it for EFI). In case you wonder, the goofy gauges not normally seen in light-duty trucks came from an '86 C65, and 87 C65, and the tach/fuel was NOS from eBay. The tach/fuel that came in the c65's were 4000rpm ones. The rest came from a '91. Tore down all three gauge panels, throughorly cleaned everything I was going to use, used the brighter IP lights, an tested each gauge before installation. Now all I need to do is figure out how to zero out the odometer without rigging my drill to it for 6 months.
