Found a great book for $5 at Ollie's today, its called "Chevrolet Pickups 1973-1998 How to identify, select and restore collector light trucks and El Caminos" its got 207 pages filled with all kinds of info from dealer and factory options to restoration tips and complete history + loads of color pics. It also includes info on S10s, Blazers and the Luv. If you don't have an Ollie's, you might find it at a Building 19, it is the exact same store.
