Hi SeriesKid,
The standard diff on a 2A should be 4.7, Defender and other later ones are 3.54 I believe. Problem with this change is that your low range changes as well so if you need a "low" low for 4wding then you lose it.
You probably only have a Salisbury in the back and the front would be a standard Rover. Have a look at the shapes and length of the nose to be certain. This should be the same as a Defender I think but that would be worth looking into more or asking someone who knows for sure
. The Salisbury is longer than a Rover diff so if you change from one to the other there are changes in propshaft required.
