I ordered a trailer hitch for my F3s and to my surprise the plates that have to be installed first to carry the hitch arm require the axel bolt to be removed which is no small task plus the thickness of the plates make it impossible for the axel bolts to be screwed back on even if I leave off the stock axel bolt washers. I think they sent me the wrong parts but its Sunday and they aren't open and I was hoping someone here might know the answer. Thanks
