Once I had the rear corners rounded out and leveled, I crossed two adjustable braces on the inside of the rear and pulled each corner in. The rear end is now about eight inches narrower than the grill area was. This required cutting a piece from the hood to fashion the rear deck. My son cut a piece of 1/8" plate to match the new curve of the narrowed deck and I used it to frame the skin of the tailgate and create the rear panel.
