What rear end parts to buy?

[NOSstang89]

The car broke a Moser forged axle last weekend at the track, so I might as well just upgrade the whole rear end so I don't break stuff back there anymore. What stuff will be happy with 5000 rpm launches with 400hp/500tq?
I was planning to upgrade to at least 31 spline axles, though I'd prefer 33 or 35. But that depends of what carrier I get... Does anyone make a strong differential that is streetable w/ 33 or 35 splines? If not, will 31's be ok? I also plan to get a rear end girdle kit and some C clip eliminators.

I need something that will be pretty good on the street, but strong enough for some hard launches. I also want something that is rebuildable so I don't have to keep buying new units when they wear out (eg., no Auburn or other gear type diffs...). Do such parts exist?

Thanks!!
