Outer Limits 4x4 Board

Just asking quickly, are all terrano rear axles limited slip ones?

The left hand side is completely chewed out and I'[ve got a joint trying to get another one to put into it, but wondering what the deal is with the axles on these.

I simply want to keep it all the same, don't want limited slip axle changing to a non-limited slip one.

not sure if all are but my 99 model definately is. Its a patrol rear lsd, unfortunately I can't tell you which one.
