Hi there, I'm new to this forum. I bought a 2000 GMC K2500HD Crew Cab with a Gas 350 that had a terrible rodknock, and a 4l80E behind it with the intentions of Cummins swapping it. I have a 1993 Intercooled VE pumped 12 Valve with an Eaton Fuller 5 speed behind it, the Cummins drivetrain is in a Ford School bus (not sure which model). I'd like to use a 47RH behind the Cummins with the factory floor-shifter transfer-case in the K2500. I already removed the gas drivetrain from the truck. I'd also like to use the factory brakes system in the truck. What do I need to get the factory transfercase to work with the 47RH, and how do I get the factory gauge cluster to work? I know the speedometer is ran off the sensor in the output of the T-case. Any input or ideas would be much appreciated, thanks.
