Installation Notes:

INSTALLATION INSTRUCTIONS - Hood

All of our products are fairly easy to install. You will need a few hand tools and a few hours of time, depending on the products you have purchased. Advanced Fiberglass Concepts LLC does recommend that a professional install for a seamless fit install these products.

Tools required for most install:

Socket set

Step 1: Open stock hood and remove bolts holding the hood down.

Step 2: Remove stock hood from vehicle. 

Step 3: Test fit our aftermarket hood by resting it on the hinge plates. Align it on each side to have appropriate lines. Keep in mind that the hood will sit high if it is not bolted down. 

Step 4: Open the hood, tighten the bolts on the hinge plates to fasten the hood down and close the hood.

Step 5: After closing the hood, it may require to be adjusted to get appropriate lines. Start by opening the hood to loosen the back hinge plate bolts and close the hood. Pull the hood in the direction you would like (To help make the body lines consistent from driver to passenger side). Slightly open the hood (Make sure to not move it otherwise you will need to restart this step) and tighten the back hinge plate bolts. 

Step 6: Repeat step 5 with the front hinge plate bolts to adjust and get the correct body lines from driver to passenger side. 

You will need to be patient to get a good fit. If the hood sits too low or too high in the front, you can adjust it by turning up or down the rubber height adjuster at the front of the hood located in the core support, or hood. If you need to adjust the back of the hood then loosen the three bolts that are holding the hinge plate to the chassis and push the hinge plate mechanism down and tighten the bolts. This will pull the back of the hood down to align with the fenders. 

These instructions are useful for all hoods sold by Advanced Fiberglass Concepts.â€"therefore some of the steps may not be needed or should be slightly altered to suit your particular vehicle and product needs.
