Update on my '02 the 6.7 flexplate is identical except for the hole in the center is slightly larger on the 6.7 which means nothing on a 5.9 scause the converter hub goes into the crankshaft anyway. The 5.9 might not work on a 6.7 though if the converter hub and crankshaft are larger. So ya they're different. Mine is bolted up and ready for the trans to go back in.
Well after some research and measuring it turns out that the 6.7 uses a different bolt than the 5.9 version. Now the center portion of it isn't exactly the same which can allow the torque converter to not be centered which can cause a vibration that would take out the pump on the transmission.

I'm just saying that THEY say it is a problem and YOU say it isn't. I understand what you are saying that the hub of the converter centers itself on the crankshaft. To be honest I have never seen the setup on the cummins so I have no first hand experience.

After further investigation the 6.7 flywheel will not work on my truck as the flexplate does do the centering of the converter hub and not the crank shaft. Stock flexplate hole is smaller than the crankshaft hole. Oh well stock one aint cracked anyway.

Well the PRW plate went on last week and it is working perfect. Fit great, no problems at all. Looks very stout too, so I don't anticipate breaking it. Would guess that it is as strong or stronger than the laminated ones out there.
