The book is a broad and detailed manual covering the entire list of restoration steps and processes, but what the book fails to account for are manufacturing differences created by the various GM assembly plants. An example is that a 65 Chevelle model from the Kansas City plant will have more undercarriage parts painted than the car assembled at the Fremont, California plant. The book tends to state "the part appears this way and this way only" on a properly restored car and makes no accounting of mid-year changes or manufacturing location difference. I certainly hope this book is never used to judge concours Chevelle restorations.For the restorer wishing to learn great deals of general information about restoring a Chevelle, this can be a good reference tool, it just needs to be taken with a grain of salt not not used as the sole source of restoration information.
