The OP's intention was to use the RAM OEM 5th wheel prep kit because his new bed already has the holes cut out. He's putting a newer bed on a '12 truck.
I'll bet it will require fabrication and modification of frame mounting points to make the OEM kit work. It could be possible, but it won't be the straight bolt-on installation for the '14 and newer trucks.
