Roof Skin Replacement....

I have never done a roof, but I have a 68 dart that has a good roof I plan on removing for future use. The car was rust from the top of the wheel wells down. Now I haven’t looked at it all that close, but I plan on drilling out as many spot welds as it takes to get it off more than likely from the inside. The other consideration is the leaded joints on the c pillar and I’m not sure but there may be some at the top of the a pillar. I know there are leaded joints at the bottom of the a pillar. I have taken apart leaded joints once with heat and once with a chisel to get the lead off. Then wire wheeling to clean up the joints to get to the spot welds, they are hard to find under the lead.

You may be best to remove the roof and support structure in one piece at the leaded joints and replace it that way although care must be made to retain the exact shape needed to nest your windshield and back glass. Lots of before, during and after measurements of glass openings need to be taken.
