A few ideas immediately come to mind:
At the top of this page is a "Links" page. Go there and look under Publications. That is a good source for books.
Have you looked in the Gallery? Cool trucks there!
Also, get you a shop manual (many suppliers) and you can see some original specs. Do a search for "resto-pack" (both with and without the hyphen) within Stovebolt. You can send away for a FREE packet of restoration information, comes directly from Chevy. They'll want your VIN, year, model, name address, etc. That is a great way to get some original spec info.
(I'm not saying my 'bolt is a picture of originality, and it is a 58, not a 57. That said, my '58 has black round mirrors, amber parking lamps (no directionals) gray/silver heater box.)
