I'm actually trying to find out the same thing, but to do the opposite. I want to swap my Pathy's R200 gears for shorter ones. I've got the V6 4WD with 3.36. I'm looking to swap in a 3.692 geared R&P, but the spline count and the input flange is what I haven't found any specs.
FYI, the V6 2WD carries 3.13, and the V8 2 or 4WD have a R230 geared in 2.93.
I was about to buy a locking M/T 370z diff, that matches the input flange 4 bolt and output flange 6 bolt of my diff and swap the whole thing. But I believe my stub axle although it is a 6 bolt even spaced, it has larger flanges.
Next option will be to see if I can swap only R&P in 3.692.
