OZ Superleggera Alloy Wheel 8x18

[Scoobysnax1963]

Hi
Can anyone help? One of my alloys has cracked. They are OZ Superleggera (GRaphite), 8x18, 5x110, ET35,Bore 65,1mm.
They are from my 9-5 Aero Estate 2002 (faclift) model.

I can't find one anywhere. I think they are also the same as the Vauxhall Vectra, but I am not sure.
Are they the same as the Ultraleggera?
Many Thanx
Mark
