Default 2005 rear diff problem question

I have an 2005 and am very nervous of beating on the car because of the rear diff issues. I bought my car with 90k all stock except for a corsa exhaust. you would think that the diff would have already been broke/ replaced.

My question is, is there a date or a number on it that I can look at and see if its the original diff?

I did an h,c,I setup on it and looking to take it to the track.

The problem with the 2005 diff is the case is not as strong as later diff cases. So when the diff case cracks apart, it pretty much obvious.

Get under the back of the car and look at the diff. You can see if it is still a 05.

The bolt pattern or tail housing of the tranny. Totally different, along with the diff itself. The ribs/external structure is way different.

Isn't another way to check if it's an 05 is that the damn drain plug on the diff is right above the leaf spring?
