different CV joints and axles can be fitted to allow more articulation. Note the 16" syncro's differences, longer shock, longer trailing arm, different cv joints.
The stock set up is often not the epitome. It depends what you want to do with the van.
Also, stock 2wd came from factory with a wide range of rear spring lengths and rates, from 231 mm to 315 mm long.
