Where on the diff are the numbers you have quoted?
If they are on the casting then I do not really know what they are apart from possible cast numbers.
The usual method of identifying the ratios (without taking the diff out of the axle)is by a small aluminium tag which is fitted to one of the bolts/nuts that hold the diff casting to the axle.

If you have got the diffs out of the axle (by undoing all the nuts that holds the diff carrier to the axle casing) then count the teeth on the pinion and the teeth on the crown wheel.
You then divide the number of pinion teeth into the number of crown teeth and this gives you the ratio of that diff.
For a higher top end speed for less engine revs you need a figure which starts 3...... rather than 4...

For more information on which ratios affect speed or torque visit the FAQ page on the technical web site at http:www.joctechnical.org.uk

... and if the figure starts with a 4 I'd like to buy it from you or swap with my one that starts with a 3.
Cheers
