Got a few issues with the diff and am waiting to hear back from MNR.

The first is fairly black and white, the mounting point on the lower passenger side doesn’t line up with the chassis hole and i am loathe to drill it out giving the turning force on it during use.

The second and slightly more annoying one is that after testing it with the prop shaft it sounded rally gravelly, like there was friction inside the diff. Had a close look today and there is definitely sand in one side of it.  Not what i expected for a newly refurbished item.

And finally, the Diff plug is sealed tight so not sure how to get it off to ensure it has suitable oil.

Am waiting on the team at MNR for next steps.
