Audi quattro Gleason /Torsen Center Differential

Hi all, as John Cleese of Monty Python has been known to say "Now for something completely different", I give you not a vintage ski binding, but the famous center differential from an Audi quattro. It&known as a "Torsen" differential, short for torque sensing. I&always been intrigued by the device, and when a friend had a spare from his race car that was already apart I took the time to model it up.
