Date code question

if only one human being out there , had had, the presence of mind , and the authority, to film the entire production process of one 1969 dart or 1970 duster. there is a production sequence of 1975 cordobas , but there is no information or explanation of the actual process or what steps actually occurred. nothing fascinates me more than the process of how these cars were put together coming down the assembly line, and how everything came together...i have about 15 more pics which can be seen at allpar....i wish i knew more about it myself...
