Get a donor roof. It's nothing but spot welds on some sheet metal. Brace the car (what's left of it) up really well drill out the spot welds. Remove the panels, prep and weld new ones on. Your going to need an entire roof. Skin, drip rails, inner roof braces, etc. You will need a nice clean complete parts car to source everything from. There will be NOTHING from those cars reused. Your basically just going to need to swap the VIN over, but it's probably rusted also.
