In case anyone was wondering how I went about creating the flared holes in the close out panel, after I created the panels and used a shrinker/stretcher to contour them to the hood I drilled a series of 1/4" pilot holes along the center of the panels. I then widened them out with a step drill bit. For anyone who has never used one these are an excellent nonviolent tool for making large holes in sheet metal. Unlike large twist drill bits they give you a nice round hole. The hole was enlarged enough to fit the center bolt from the punch/flare die. The two halves are then tightened down until the hole is punched and then the subsequent flare is formed.
