Hy HFfarms, yes there are parts books they usually cover a range of years and are usually split into light trucks, medium duty trucks and heavy duty trucks. They can be a mystery until you learn how to read them. They are not necessarily consistent, for example sometimes there will be a reference to the original manufacturers part numbers,casting numbers, or stamped numbers and sometimes no reference at all. If you can locate a parts book which covers your year and size of truck, I would buy it. You can learn to read it as you work on your truck, good luck.
