3. To save space, I'm not showing you the four 1/4-inch Allen bolts and nuts that were used to assemble the two pieces of the cold-air dam. I'm also not showing you the three angled steel brackets that are attached to it. Those brackets and one of the holes in the bottom of the dam are used to attach to the factory mounting points on the inner fenderwell, as well as the core support. The hardware is left loose for the time being.
