Chris,
A book that includes all the Detomaso cars you are looking for (although not "indepth") is a great picture book called "Detomaso Pantera" by David & Linda Adler and Wallace Wyss. It covers the cars you are looking for and has many color photos. The best item ever printed on the Pantera Si is Detomaso's own sales brochure on the car. The photos are spectacular (in my opinion). "Panteras for the Road" by Rassmuesen is another great picture book on the early Pantera/Mangusta/Vallelunga. Detomaso also produced incredible sales brochures on the Guara that have great photos of the car.
Hope this info helps!
