yes Chris but you need to swap the hubs too, i did think you could get away with the xr driveshafts though, seeing as alot of the 4x4 cossie boys fit em to there cossies coz there longer ?
re fitting the 4 pots to the 4x4, personaly i would risk grinding the TRE but if you are willing to do this they do fit
the 4x4 caliper/2wd conversion i mentioned only works on the 2wd
