HFfarms,
If you absolutely must have a printed book, you will have to search the web (primarily eBay) to watch for sales as they do come up occasionally.
As Gord noted above, the "GM parts wiki?" link is a great source, but some find it difficult to search if you don't use the correct words/information for the parts you are searching for.
An alternative in the form of a CD can be had here (not mine)
Chevrolet Parts Book. They are also available elsewhere, just do a web search and you will find them. Prices vary depending on seller.
You just need to have a computer with a CD/DVD capability (or you can purchase a remote CD/DVD device to connect to your computer like I use with my laptop).
There are currently a number of CD/DVD devices available on line through Amazon for less than $35, which are simple plug and play units.
Good luck in your search!
Dan
