R200 stub axle length

[caperix]

For the rear of my car I am thinking about doing a ttt stub axle eliminating setup with the factory long nose r200.  With this setup I will need to change out the stub axles to ones that will fit the axles I go with.  There are a number of options with the correct spline count, early j30, open 240sx & na z32.  I can not find any length comparison though to see how they will fit the long nose case.  I plan on running a m factory limited slip the the longer stub for the vlsd should not be needed.  Additionally does anyone know if Nissan used the same CV shaft spline count on all cv's?  They were made with a 3x3 a 5 bolt & a 6 bolt mounting pattern at the stub, but I do no know if the shaft changed.
