Caliper carriers are the same for 4x4 and 2wd. Stub shafts I'm not sure, as the 2wd uses thicker driveshafts with 108 mm flanges in stead of the 100 mm of the 4x4. But I don't know if that is on both sides of the driveshafts, or only on the diff side.
Had a feeling the rear arb where different on the 2 models i will be using 18mm bar on my rwd set up,caliper carriers i will also use just need to know if the stub axles can be used or if i have to get 2wd versions.
