99 vs series 3 ute diff id

[Forrestp]

Hey all just joined the sight and loving it!! Any way I recently got a new ute so I could focus on my Hr project car and am curious about my diff... Someone once mentioned that the series 3utes all came out with an LSD but I find that hard to believe so I am wondering are there any tags on my diff housing that will tell me what I have got?? On the housing it has in raised letters m2j5 and the BTR E and a code on a tag that reads
92034574 do these mean anything??

Any info would be great

Cheers fp

if its lsd there should be a tag sayig high performance differential, or lsd fluid only. then their should be another tag saying 3.08 ratio. these are found on the diff cover
