if you heat up that lead you can remove it...there is a lip that the pillar laid in and then was welded and filled with lead...what prob happened is water from the holes above the door got in and rusted it out...if you heat up the area around the A pillar right at the top where it meets the roof...there is more lead. from there it is just drilling out spot welds to remove the roof...along the inside of the door, hatch, and along the top of the windshield...actually under the windshield gasket.
