Thread size for tow eye on a 200

Hi guys,

Not sure if this is in the right section but does anyone know the thread diameter for the front tow eye on a 200? I'm after fitting a tow strap and looking for a suitable bolt, been in touch with marshall but it seems that he has stopped production now so I am looking at maybe trying to fabricate/(more like bodge together) one up myself!
 
If your wanting one to cut/weld onto a strap the ones from an 02/03/04 laguna have the same thread.
