This is a set of two service manuals and a wiring diagram manual used by Ford technicians.  You will receive all 3 manuals of the set:  volume 1, 2 and the wiring diagram book.  They have way more detail and information than a Chilton's or Haynes manual.  They are used, but in good condition.  All the pages are present and they are easily readable (see a representative page in the photos).  These were written by the Ford Technical Publication Department.  See photos for additional details.
