GTO Differential & Positraction Unit

[NBM LS1 M6]

What type of differential unit and positraction unit is found in the GTO? Is it the same size and type differential and posi as found in the 4th Generation F-bodies, or is it some wierd type of Aussie technology. I'm NOT talking about solid axle versa independent live axle, but the size and type of differential gears themselves. If I buy a GTO, I might be strongly inclined to install a full race Torsen posi unit if possible.
