I have a 94 5.9 magnum. Manual transmission. Started looking into replacing my engine in my 318 power wagon. The stock flex plate for 94 has no weight. 96 and up is weighted. The crank sensors are different from manual to automatic so be sure to verify the sensor is for automatic. But if convertor outfit is supplying,you are ahead of the game. Would be dilligent to ask the builder what year crank you should be dialing in for.
