All H233B Axles aren’t the same, they do come in a few different widths but the main difference in the differential itself, is the spline count and diameter of the axle shafts. The H233B comes in both 1.26″ / 31 Spline and 3.31″ / 33-spline versions. however the gear sets and 3rd member housings are interchangeable.
Here is a little bit better breakdown of the H233B and which trucks it came in:
Pathfinder / Terrano: Late 80’s to 1995 – 1.26″/31-spline
Pathfinder: 1996 to 2004 – 1.31″/33-spline
