I have found that the Ford Motor Co 1940 chassis book and body parts book quite helpful for restoration info. The green bible is helpful for non concourse cars.
They make reprints of the owners manual that came in the glove compartment. The 40 book by the EFV8 club is misleading on many details, when the new one comes out it will be vastly superior. How will your friend use them, or how detailed info does he need?
