CRG gets most of it's information from actual unmolested cars, and literature (order forms, brochures, protect-o-plates, etc.)
There are lots of books out there, but I have found some to be inaccurate. There is one book that focuses on the SS cars in general (including Impala, Chevelle, Nova, Camaro) called Chevy SS, or something similar.
There's another called *The Camaro Whitebook* that lists the standard features and all options, year to year.
