Corvette Black Book
My suggestion is you go to your local bookstore and purchase a "Corvette Black Book" a handy pocket-sized paperback that covers all the years. Great reference guide, covering paint and interior options, and identifies engines, carbs, distributors and alternators as well. I think it's about $23. Money well spent.
Unfortunately, I am deployed to McMurdo Station, Antarctica or I would provide you the ISBN so you could order one if not in stock. Maybe someone else can help here.
