Part replacement because of rust

[burbygurby]

I need to replace these two parts because of rust but don't know what to search for in terms of finding a replacement so I was wondering where or how to find that specific piece. Its a 73 mach1 one and the parts needing replaced are in the photos behind the rear seats.

Not sure what those would be called. It looks like you could cut out the rusted sections, get some weldable sheet metal, and patch those area with the new sheet metal.

Package tray or package shelf? I’m not sure anyone is making that.

You'd have to get sections removed from a parts car. Maybe @Motorcity Mustang has a car with a good set?

If not, I'd remove the rusty parts and fab up some patch panels.
