Well, depending on exactly where the body it in Nova Scotia, I found that, for us in British Columbia, it is about 3900 miles to Halifax, NS.... and "only" about 3700 miles from Los Angeles, CA... From New York City, it is about 900 miles to Halifax.....
I don't think there are actually big customs issues on the (probably re-)importation of a US built car body into the USA....unless one of the Border BOZOs makes it into one.... there is a deal regarding all North American built cars (as well as many foreign ones) that, under NAFTA - the North American Free Trade Agreement - exempting ALL vehicles that are over 15 years old from FEDERAL safety requirements.... I know that bringing vehicles north into Canada is only a matter of having paperwork in hand and pre-clearing the exportation of the vehicle with the US Customs - and paying our taxes up here too - but the last vehicle I brought in to Canada was an incomplete 20 year old Harley which, due to my being away for long enough to bring in a maximum tax/duty free exemption, I paid NO tax.... Your US Gov website should have links to the relevant US Customs websites for information on what you may need to know or have to do to import something like an old Ford car body.
