You can easily just grab the flexplate with the 5.9 (360) and that will allow you to use your neutral ballance converter. You will only need to slot one torque converter bolt hole slightly. Easy peasy
Was just going to say....a flexplate is pretty cheap to fix that issue. Most aftermarket converters are neutral. You just get an external balanced flexplate.
