This flywheel is what you want:

I'm running this exact part # in my 88 dodge with a 2001 5.9 magnum with all the original MPFI. While it is chinese and there are other manufacturers, this part number will fit a 95 5.9 so that you use a 99 nv3500. There is only 1 flywheel for a 5.9 magnum and only one for a 5.2 magnum from 92-02.

That said, I think the 5.2 is scalloped and thats a whole other bucket of worms.
