Zafira A subframe

The other day i snapped a spring, my mechanic was having a look under the car and decided to remove the plastic tray and uncovered a nightmare.
The subframe is so badly rusted that everything has started to bend and there is a massive hole. It was crumbling away in his hand.
What im trying to find out is, does a subframe from an Astra G fit the zafira A?
Thanks all.
