Hi Rob,
If your car is anything like my Duratec the sump is specially made and nothing standard will fit. The plug is a shouldered bolt M12x1.75 from memory and the washer is a bonded washer (which can be used several times) and cost pennies
Here are a couple of piccies.
If I can help more let me know.
Regards
