ive done alot but costs about £300 in parts which may mean its cheaper to buy one as you need abd are specific to 110 ,discs ,calipers .caliper mounting bracket ,stub axles,half shafts,wheel bearings ,hubs ,drive members are the same as 300 tdi def or disco front cab give you numbers if you want ,just bolt on parts
all salisbury rear axle tubes can be either drum or disc ,the only difference is that disc axle has a hole on shocker mount for back plate but i wouldnt fit back plate anyhow so yes
same 3.54 ,all gear differences are made up in transfer box
