It looks to me like you only need the half panel for the lower section. That is a good thing because those are actually formed to fit correctly. The full panels which I have bought are not even close to fitting at the bottom. So much so that you would be ahead of the game just buying a random piece sheet metal rather than trying to correct those incorrect full panels. Maybe some day a vendor will make the full panel with the correct bends at the bottom. I have been holding my breathe for 30 years...
