I used a cutting wheel on a air tool, hard to cut a round hole with a straight disc but take your time and comes out good. I used black door edge guard from the local parts store to cover up the edge. I centered the hole around the air cleaner, not the center of the hood. Remember, the engine is offset in most or all mopars.....but if a scoop is installed, then the scoop is centered on the hood :glasses7:
