Do some searching on the Quaife and see what you think. They are based on the torsen differential. They are very unique in that they can shift torque back and forth and they shift the torque to the tire that has the most traction. If you have ever ridden in a car with one that is spinning the tires you can actually feel it searching for traction.
Here is one that fits a C32, CLK55 and Chrysler 5.7 Hemi (210 axle):
