One of the best, if not THE best manual published for our trucks. There is also blazer and suburban and van info and procedures in this book. It's truly a must have book if you work on your trucks at all. It's in fair condition, the binding is just starting to separate, but there are no loose or missing pages I could find. $25 shipped.
I also have a Chiltons Manual for 1972-1979 that covers the american makes of cars. $10 shipped.
