My brother has since sold the truck, but he used to have a 93 dually Gen1. He found a mechanical tach gauge from an old 60s perkins equipped Dodge truck, went to an IH dealer and bought a valve cover with the oil fill cap on it, and a mechanical tach drive kit and cable for a 4bt engine. the drive went into the cover where the filler pipe used to go, and connected through a link to the injector pump timing gear. he routed the cable into the truck, and instead of butchering the original cluster, he went to a wrecking yard and got another one that he modified to fit the tach in. it came out pretty neat.
