Definitely need a different flex plate. The 5.9 is externally balanced... 3.9 is not.
Will have to have the computer re-programmed for the 3.9. Crank sensor signal is different, and there are two less cylinders..... V-8 programming won't run the six at all. You might be better off finding another 5.9 to drop in there, probably end up being cheaper.......
