Some of the 1970 cars I have seen so far that were exported to some countries with incomplete VINs. Bodies built at the Hamtramck plant & then shipped overseas incomplete for final trim out once they arrived.
In Schinznach the cars were fully assembled. Sheetmeal was delivered from a plant in Rotterdam, Netherlands. Engine and Transmission and other technical components were shipped from US. Parts of trim and interior. Front and rear glasses were Swiss products.
