Here are a few pics of my biatch atm.....

You can see the teeth that were ripped off the gear inside the original diff. It's these teeth that do all the damage to the diff/gearbox casing and on rare occurance, the gearbox internals. I can't see behind the old diff as it isn't removed yet to see how much damage if any, has been done by the teeth.

The photo of the origninal diff and crown wheel show that I have disconnected the right side flange which holds the driveshaft in place. In these cars the driveshafts are in two parts (an inner and outer). The left inner shaft is only about 200mm long whilst the right inner shaft if more like1200mm. I think I need to remove the right driveshaft now, which is going to be a pain. This will release the diff from its housing.

For those interested, the original diff has two holes on either side (you can see the bottom hole in the photo below. The teeth are spat through these holes and this is when the damage occurs. If you ever lose drive in your car, immediately pull to the side of the road and turn it off. Don't try and catch a gear or test, as this can cause more extensive damage from more teeth being spat through these holes. Should the Q2 diff ever fail, it is a lot less likely to cause further damage as there are 4 holes around the diff (you can see two in the photo below- me holding the Q2) and they are very small. The pieces I pulled out of the casing are larger than the Q2 holes.
