Gauge Pods[edit]
Over the years there were many options for the Z31 for Gauge pods. Lo-Tec Used to make a Pilar with 3 pods for 52mm gauges in the Z31 but it has long been out of production. They come up sometimes on ebay bit that is rare.
Other Pilar options are from RMFG or you can modify one from an early Mitsubishi Eclipse to fit. Single Pods are Autometer part # ATM-20601 or ATM-20600 for the Dual Gauge Pods.
Some People also would replace the Factory center gauges with aftermarket units. These would be the 2 5/8″ size to look right without an adapter but you can use 52mm (2-1/16")As well with adapters.
Adapters can be purchased from The Z Garage.net
