After we had solved the earlier problem it was easy to slide off the rear body section.

The worst areas regarding corrosion were as we suspected/knew the egde of the wheel arches.

The roof and boot sections looks flimsy compared with the doorpost and wheel housing.

The End

Conclusion: Leave the rear body section on. Unless you not are in desperate need of therapy or the car is in a very bad state. For me it´s therapy. Growing up i an engine repair shop it makes me calm to see thing being completly dismantled.
