Ford produced shop manuals in several volumes for the dealership service department technicians on a yearly basis. Each volume targets a particular area such as body, engine, electrical, and so forth. I purchased a 5 volume set for 1980 Ford Pinto for about $70. You can buy just one volume which tends to go for $28 to $32. The volume pertaining to body would be the book you want if you do not wish to get the entire set. It's useful with part numbers, step by step directions, pictures, and diagrams. It's different than Chilton's shop books. I brought mine through eBay. If you cannot find it, you can try Auto literature retailers. If you want me to help you find it, let me know the year. Your pics looks like a 71 or 72?
Happy Motoring,
Dan
