Fellow listers, I need help on this one, is a 200q20v gearbox a 016 gearbox type? If yes, would it be possible to swap the Tor$en center diff for a good old locker from a 4kq to use in my '85 coupe quattro? What's the 200q20v's final drive? Is it a 4.11 or a 3.89? How hard would the swap be? Thanks for any input, Regards from Belgium, Mihnea
