I kind of stumbled upon this book accidentally in 2020 and love it. I grew up with these cars purchasing my first TA new in January of 73. I followed the publications every year tracking the changes, but still learned quite a bit from reading this guide. As others have said it is not a service manual or an exploded parts book. It does have a lot of details about production and various option changes through the years. A lot of research and hard work went into the creation of this book. In Rocky's own words, "this isn't just another Firebird book". While it does have nice color photos, this book tells the detailed story of the second generation Firebirds.
If you love these cars, you will enjoy this book. Don't let it get away again.
