Late MK2 Focus Estate rear springs

[2Btoo]

Guys,

Quickie: I have volunteered to change the rear springs on a friend's late Mk2 focus estate. One is snapped and it's failed an MOT.

I can find lots online about rear springs for the hatchback version of the car but just about nothing about the estate. Is the estate suspension different to that of the hatchback and is there anything different that I need to know about changing the springs on one?

Thanks.
