Outer Limits 4x4 Board

I've had a look on here and found that my bundera (2LT motor) should have a 4.88 rear diff...

Is this diff the same as any other toyotas? i'm looking to replace it with the same or even a slightly lower ratio but dont know much about it.

i figure it'll be easier to by the same hilux diff (if it exists) rather than one out of a bundera.

Pretty much all the petrol luxs have a 4.88 diff ratio.
