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.
