IS300 and Altezza rear end differences?

Sorry if this has been brought up before, but I searched for a while and couldn't find a clear answer. Can someone tell me the differences between the rear end of the is300 and an altezza? Specifically, are things like the differential, axles, and the differential case the same between the two cars? If not, what is different and how is it different? Can a lsd made for an altezza be bolted into an is300 like oem, or do other things need to be replaced/modified too? Thanks in advance.

the diff housing, and all that is the same. In fact, most of the rear drive toyotas share a lot of the same components out back. The supra for example shares a number of rear diff parts with us.

As for the suspension arms and such, that's all the same as well, or at least they are interchangeable. I do not know if there are any differences between the brakes or the suspension arms for sure, but I wouldn't think so.

For example... the rear member braces from Tom's and TRD all fit the IS300.

In terms of differentials, they're the same housings with different gears/lsds.

OEM is best.
