1. Preparation:
* Gather your tools: You'll need various tools including wrenches (metric), sockets, screwdrivers (Phillips and possibly flathead), possibly a ratchet and extensions, possibly a torque wrench, and possibly a fender alignment tool (highly recommended).
* Clean the area: Thoroughly clean the fender mounting points on the car's body and the fender itself. Remove any rust, dirt, or old paint that might interfere with proper alignment and bolting.
* Check parts: Ensure you have all necessary bolts, nuts, washers, and any other hardware required for mounting the fender. Compare your new/repaired fender to the old one to ensure everything is identical. Missing parts or incorrect parts will cause problems.
2. Mounting the Fender:
* Align the fender: Carefully position the fender on the car's body. This is the most crucial step. Start by aligning the top edge of the fender with the body line. Then align the fender's inner lip with the body's inner structure. Use fender alignment tools (highly recommended) or shims to ensure the fender sits flush and evenly with the body. Take your time and be precise. Minor discrepancies here will be amplified when the fender is bolted on.
* Start with the inner bolts: Begin by loosely attaching the inner fender bolts. These bolts typically attach the fender to the inner structure of the car. Don't tighten them completely yet.
* Attach remaining bolts: After the inner bolts are loosely in place, carefully align the remaining fender mounting locations and install the remaining bolts. Again, don't fully tighten any of the bolts until the fender is fully aligned and all bolts are in place.
* Adjust and tighten: Once all bolts are installed, check the alignment of the fender one last time. Make any necessary adjustments by slightly loosening and repositioning the fender. Once you're satisfied with the alignment, tighten all bolts securely and evenly, using a torque wrench to ensure you don't over-tighten and damage the fender or bodywork. Consult a shop manual for the proper torque specifications.
3. Additional considerations:
* Inner fender liner: The inner fender liner is usually installed *before* the outer fender. This provides some support and helps with alignment.
* Rubber bumpers/bump stops: Many fenders use rubber bumpers or bump stops to prevent rattles and provide a bit of cushioning. Make sure to install these correctly.
* Fender to headlamp alignment: Ensure the fender correctly aligns with your headlamps.
* Repair work: If you are replacing a damaged fender, you may need to do some bodywork or paint repair beforehand to ensure a clean, professional-looking result.
* Shop manual: A 1976 Corvette shop manual is an invaluable resource. It will show you detailed diagrams and procedures for removing and installing the fenders, and will provide important torque specifications.
This is a general overview. The specific details may vary depending on your fender's condition, whether you are reinstalling an original fender or a replacement, and the tools at your disposal. If you're unfamiliar with automotive bodywork, seeking help from an experienced mechanic is highly recommended. Improper installation can lead to alignment issues and potentially damage the fender or the car's body.
