Thats about right. On the front cover there might be a number that starts with 330-?? You HAVE to make sure it is 10-30 series though, I bought an S-10 one of Ebay, since I saw no picture, I had no way of knowing. Both are called light duty truck manuals. Also found there are "preliminary" service manuals, like I have, that left out things like the transfer cases. They really are only worth what you are willing to pay, $25 is usually my upper limit.
