Martin - I work in a parts store in the US, and I can get as many replacement studs and lug nuts as you need, brand new from Dorman. Probably about $2 apiece. If you only need a few, postage may cost more than the parts themselves, but shouldn't be TOO outrageous for a small package. Shoot me a PM if you can't find them elsewhere. We've got everything else for a fox, too: chassis parts, engine gaskets, brake parts, whatever you need.
