ionicdynamics makes them in figerglass or carbon fiber.
Boost gauge goes there.
Everythign else (Oil pressure, fuel pressure, oil temp, water temp) is run thru a heads up display, the Defi VSD Concept which is flush mounted on the dash hat above the gauges. If doing oil pressure and oil temp i reccommend a oil sandwich plate. it fits in between the oil filter and the oil pedistal. They are about 50-80$. Makes life easy.
EGTs are just probes and will be run into the Zemulator.
