Most of the work is done. You'll need to deal with the headliner anyway so treat the rust as you find it on the inside of the body panels. Those solutions that chelate the rust away make fast work of rust removal if you can get a flow of it going over the rusty areas for a few hours. Less damage to the steel, too.
There is more steel there, though. The rear 1/4 panels were X amount thicker than the Mirada/Cordoba cars.
My 5th Ave had foam still mostly stuck to the backing of the A pillar covers and the B pillar piece I recovered. I removed just the cloth material off the foam keeping most of the foam intact. The areas where some tore off aren't very noticeable after its been covered with new cloth. I used 3M spray adhesive on the backside, be sure to test the adhesive's tendency to melt the foam before large application to a concave area.
Nice combo, black with gray.... no pesky moonroof, already carbed... doesn't get much better than that.
