One of these babies will raise the fan hub about 4" on the front of the engine and bring it over the centerline of the crank. (Cummins Fan Support 6bt- 3913433/5263160). It will necessitate a slightly different routing of the fan belt, adding a new fan/pulley mount for the ACS fan and a 1" spacer to kick the new fan out yet another inch so it clears the front of the engine. See following pics.
