If it's the soft-cover, 8 1/2 x 11 format book with a red coupe on the cover, then I've got a copy (can't remember the author's name--I'm at work).
It's certainly a help, but I'd say there aren't enough clear photos and some information is probably not entirely correct. It was a surprise to me when I came back into the 'fold' after restoring a mid-year Corvette, how sparse the information is that's available on Firebird restoration.
A guy by the name of M. F. Dobbins has produced several editions of Corvette restoration guides in the same soft-cover format that consist primarily of clear, black and white close-up photos of relevant parts as installed, particularly chronicling the differences from year-to-year. A separate section at the back lists fastener sizes, head markings (Corvette people are fanatical) and finish as well as the correct finish for under-hood/under car areas, including varying levels of gloss black.
This is a monumental undertaking that required access to many original or confirmed 'correctly' restored cars. Moore's book is certainly a start, but you'll need to be fastidious in taking photos at car shows, watching for any literature of the period (ie: car magazines that have road test reviews with photos), talking to other owners, and asking questions on this board.
I'm a relative newcomer here, but I've already been helped considerably by other members posting information and sometimes photos of their original or properly restored cars as a reference.
