How Do We Install Rods That Go In Front Of Hemi Dart Scoop?

Hi everyone. I got my AAR Fiberglass's Hemi Dart Scoop painted and ready for install. Bought some 3/8 inch aluminum rods from Home Depot. Cut to length, use tap and die to make threading on rods to put nuts on. But my question is how do we install it??? How does it stay on. Don't think we drill a hole through the scoop Looked at pics online of different peoples rides with the same scoop. NEED HELP AND ADVICE. :sad:

Thanks!!!!!!!!!!!!!!!!!!!!!!!
