There are two parts manuals. One included drive train and other components made by the Ferrari factory. The second parts manual was written by the Scaglietti factory which included the skin and sundry parts put on the car. The manual you see here was written by Ferrari. The Ferrari parts manual would fit inside the manual pouch. Supplements to the parts manual were added as design changes and DOT evolved. The first printing was 1969/71. An accurate reproduction parts manual is satisfactory for concours.
