* Bed to frame bolts: These are typically large, high-strength bolts. Sizes commonly range from 7/16" to 1/2" in diameter, and the length will vary considerably depending on the location.
* Bed side and tailgate bolts: These are usually smaller than the frame bolts, often ranging from 1/4" to 3/8" in diameter.
* Internal bed bolts (for liners, etc.): These will vary widely depending on what's being attached.
To find the correct size:
1. Identify the specific bolt: Determine *exactly* which bolt you need to replace. Take a picture and note its location on the truck.
2. Measure the bolt: If you can remove a similar bolt, measure its diameter and length. The thread pitch (threads per inch) might also be important.
3. Use a bolt gauge: Hardware stores sell bolt gauges that can help you quickly determine the size.
4. Check a parts diagram: Use a parts diagram for your specific 1997 Chevy truck model (there were several, including Silverado and C/K series) to find the part number. This number will help you get the right size bolt from a parts store. Your truck's VIN can help in identifying the exact model.
5. Visit a parts store: A local auto parts store can usually identify the bolt based on your truck's year, make, and model, and even the location of the bolt. They can also provide the correct size and length.
Don't guess! Using the wrong size bolt can be dangerous and lead to damage. Take the time to properly identify the bolt you need.
