Hello,
My Transit camper has alloy wheels and M14x2 wheel nuts, which have flat seats and are capped with some stainless steel cover. These nuts are to be loosened/fastened by the original tool or else they are ruined easily. This happened to some of mine. So, I seek for replacement nuts. 3-5 nuts would be fine. They are quite expensive to buy at Ford, so I hope you have some used ones for sale. I live in the Netherlands, but don't hesitate to contact me if you're not.
Kind regards,
Ronald
