S2 header tank/expansion tank

[clarkmagpie]

Afternoon chaps,

I've been struggling with a water leak on my S2 52 plate Elise, after much searching it appears that the header/expansion tank has got a crack in it.
Has anyone got any ideas to where to source one from?
What model rover/MG would have the same?

Thanks

MGF for starters and probably a number of different MG ZRs.
