Hi,
The manuals you are looking for is on this website.

Air Corps Library is a online service, supplying factory aircraft drawings, flight, maintenance and general manuals for the aircraft restoration industry and historians. You have to pay a yearly fee, but they have the Navy sheet metal manuals. I don't know, if they have all of the manuals, that the Navy printed.
Cheers
Bill
