The '96+ 5.9 flexplate has the balance weight on it. If I am understanding you correctly, you could locate the later flexplate and use your 5.2 flywheel then.
Basically you are correct but I really don't want to move the flywheel further to the end of the register. If i could do it again I probably would have taken a 5.9 flywheel an had the
outer circumference milled down to accept the 130 tooth ring a had it redrilled and tapped for the 10.5 clutch.
