[Too Many Projects]

A little more "get ready to lift the body" work. As of this afternoon, it is ready. And I received a set of all new body cushions and fasteners today. I need to load the rotisserie on the trailer and bring it up to the front shop building.
I started sanding on the roof to quarter seam to expose the lead and melt it out, but there is no lead ?? The filler feels like a plastic. It's very dense and hard. I chopped most of it pout with an air chisel. Anyone familiar with this, or has the lead already been replaced ? It doesn't seem that way, as the original white paint goes right up to the seam. I'm going to sand more carefully on the other side and try to determine if it is original.
