Would be easier and cheaper to just use a diff from a 2.0 XR4x4 I would have thought.

Don't know the tooth count, but the 2 litre DOHC XR4x4 came as standard with a 3.92:1 LSD

You can fit the 7" cosworth lsd centre into any 7" sierra diff, open or lsd. just transfer the centre and the output flanges over to the other diff.
7 1/2" centres do not fit the 7" diff
