I'm working on my '65 right now. Going for a 60's custom look. I think one of the best things you could do would be to get magazines from the 50's on up. Stuff like "Rod Builder", "Custom Cars", "Rodding and Restyling", "Rod n Custom" and of course "Hot Rod". There's plenty of others too. Check ebay. There's always a ton of 'em on there.
