The left side is easy, rework what's there. Just use standard metal working practices. The right side appears to have sustained greater damage. The double layer inhibits dolly placement for proper manipulation. But you can attempt it if you are confident with your abilities. If you have a donor hood cut out the right corner and replace it. Just drill out the spotwelds and R&I. Practice proper welding to minimize warpage. I just performed this procedure recently, piece of cake. Additionally, people have a compulsion to stand hoods on those corners. Perhaps they feel it looks better displayed that way. They stand just fine on their sides. I've repaired a few due to the corners being damaged. And seen flawless hoods rot there because they were left outside on the ends. Apparently you have no recourse with the shipper?
