I have seen D2's 'repaired' with the wrong gearbox before now, but probably not recommended.
On front wheel drive cars you have only a gearbox code, which includes the final drive ratio for the front wheels in the box.
On quattros you have 2 codes, one for the box, and one for the rear diff.
Get the right gearbox code and all will be well...
