Just passing and saw this as a former Eibach owner I can tell you the body kit for your car was made by Visteon in the US. These kits are widely sought by Cougar owners in the US and there are a variety of options available. You should check here and even on a variety of US parts sites and see how you go, you may not find the exact one.
