I've done several of these.
Tip 1

don't use the Blair cutter on it. It will just chew up a nice cutter. get 4 or 5 harbor freight cutters. They last longer on rusted panel than Blair's do and cost a fraction of a blair. Blair works vey well on clean metal but not so good on rust

Tip 2
cut off as much of the roof as you can and as close to the drip edge as you can leaving the leaded portion at the A pillar intact, you can do this later.
you will have to cut above or below the lead joint, unless you chemically remove the lead. If you try to mig over it even after melting it out, it makes a mess.

These can be weld bonded back on. and spotted every 8 inches

I cut them with a plasma but its a 30 unit. you should be able to use an electric shear or air shear for the majority of it. stay away from air chisels they will damage more than the cut off. most everything at those spot is rusty or weak from age and a air chisel will deform most of the edges
