Brian,do not be confused between the Shop manuals which have a multitude of more generic information for a variety of Ford models and are invaluable for maintenance and the assemblyline manuals which are specific to the Mustang and show assembly illustrations how the cars were put together along with the nuts,bolts,screws etc.used to do it. Both sets are invaluable for any Mustang owner especially those that maintain their own vehilcle and want to make their car more assemblyline correct. It is a common misconception that both terms "shop manual " and "assemblyline manuals" are to discribe the same thing. They are 2 different sets of manuals with different information.
