1930 Below Deck Panel Removal/Replacement

[Steves46]

The below deck panel on my 30 Coupe is cracked & splitting along the bottom and needs to be replaced. Alothough when I am underneith I can see at least 3 bolts on the right/left flanges, I am sure there are others. For removal of the panel, does the rumble seat lid and curved panel need top be removed first? Just want to be sure so that I don't start unnecessarily removing stuff. If I do need to remove these components, is there anything I nned to be aware of? Appreciate the guidance. Steve
