Front axle will fit, check whether the donor disco is 200 or 300tdi, that affects what width radius arms it needs. What year is your 110? The callipers may be different (dual circuit types) but you can transfer your current ones across.
It would be worth changing the spring retaining bars, shock turrets and spring seats depending on the condition of your current items.
The back axle will fit also, however it may not be as strong as your current one (depending whether you have a standard axle or a salisbury) The spring seats are different sizes, but if your old ones are ok then you can use them on the new axle. You may also need to change the prop flange on the rear diff depending whether it is a 4 bolt or the 3 bolt version with the silly rubber doughnut.
