67/68/69 cuda dilemma

The LH side of the trunk has perforation and some rust peppering that is also perforation. I just have not pushed it thru with a pick yet. The yellow outline is what i will have to cut out. The structural framework on the underside is a bit worse. Its rotted completely thru about 5" across right where the seam is. It's all made of 19ga mild steel sheetmetal of which I have a 4' square of for fabbing repairs so its pretty easy to make new pieces. Theres also a few small screw holes in the top of the trunk lid on the left side like somebody was trying to mock up a sheetmetal spoiler and abandoned the idea. That's maybe how the water got in and rust ate only that one side. I will weld up and grind those holes down too.
