Rear Differential Help/Info, 38311-43F10

[240srCoupe]

I have a JDM rear differential with part number 38311-43F10, google searching leads me to believe its from an R32/R33 Skyline or 180SX with all wheel steering. Can anyone help me out on this subject?? I just need to know what the differential is from so Ill know what type/gearing it is, its definitely not an open diff...

Any help is greatly appreciated.

Turn the input shaft and count how many times it takes to get the outputs to turn once. Should be 4.11 or 4.36ish.

Turned the input shaft and its right at 4 turns to 1 rotation, not less than 4 at all and not quite 4.5 so Im guessing it should be 4.11 gearing??

That sounds right.
