Turn signals were typically located in the front and rear fenders, and later models included them in the taillights and headlights.
To be more helpful, I need more information about the Chevrolet truck you are referring to. Please tell me:
* Year: What year was the truck manufactured?
* Model: What model of Chevrolet truck was it (e.g., Silverado, C10, etc.)?
With this information, I can give you a more accurate answer.
