I got this on my later purchase, got a T2 and it came with a MIP tranny. When I opened the case, it had the incorrect diff in it.
Long story short I found the MIP diff on the T2 tranny and I discovered the T2, GT, B4 and T4 tranny diffs has the same teeth count as the old MIP changebox tranny.

Anyone knows how to get this old tranny case whiter? Peroxide?

I think you can use the newer diff on the old MIP if you sand it down and make it thinner.

I don't have any manuals or any more knowledge on this so any more info on this is welcome.
