Someone decided it needed a nip and tuck, so they drove into it. :finger: took out the rear diff and bent the trailing arms etc

There is no hard and fast rule to diff ratios... some manual 4.1's came with 3.9, some with 4.1..
You just have to look and see, or make a call to the holding yard..

3.0 GQ's came with 4.3's... New $930ish each end from Nissan.

also early model leaf sprung gq utes, however i think they all have the monster rear diffs, maybe incorrect?? so ring gear would be too big unless you want the whole axle housing and all

Check inner guard just behind D/S headlight....there's another plate with HG41 or whatever. Here D/S is RHS.

Good luck!!
