"Valiant Effort" - Wintermute's '73

I know the '70s weren't exactly the pinnacle of build quality, but a 5/16" drop from the trunk floor to passenger side extension!? (It's much closer at the ends of the panel at least) I guess enough seam sealer will hide anything!

When it's time to reassemble the pieces, I'd like to make it even all the way down the seam. Hopefully this won't screw up the location of the bottom edge of the quarter panel.
