Diff oil is better known as hypoid gear oil, this is available from car shops and motor factors, it is generally available in 75/90 these days, and this is suitable for your vehicle.
If you are changing it, buy 5 litre cans as well as a 1 litre top up bottle with the extended spout to fill the diffs up.
