Simple fact is you need both Dave's books and the Francis/Deangelis book if you are serious about 32 or early Ford stuff in general. Dave's books serve as your #1 go to for restoration of 32 period. The Francis book is interesting in several ways, one is the info that is not in Dave's books but in the fact they were at Ford in the engineering department. Although not there during the 32 period, they do have real life knowledge of how the engineering and documentation process actually works in a large manufacturing company. I came from this kind of background (not at Ford), but the "way it really was" should be enlightening to those that like research in this old stuff. A simple fact that they expose is if you solely research drawings from engineering you do not get the whole story. A signed off drawing doesn't mean it happened. The whole process of drawing sign offs, release notes ,manufacturing engineering documents and finally production engineering documents and implementation schedules need to be reviewed if you are trying to really figure something out. Add in errors and omissions and the view can be further clouded. So for you guys that do your own snooping and have copies of the drawings from Benson, be somewhat careful. The fact that a drawing was signed and released on such and such date may not mean that much without the other stuff.
