Bob - running coilovers on these cars in the rear requires some modification to the sheet metal in the area where your springs are interfering.

With coilovers the torsion tube has less to do, as it isn't being twisted in the middle by the torsion bars any longer. But that part of the torsion tube still takes up significant braking forces, and acceleration forces, and those tend to try to twist the tube first one way, and then the other. In general, I'd say it is simpler to weld in reinforcements by the inner suspension pickup points to counter these twisting forces.

Do you suppose your steel banana arms, or one of them, were bent in the crash?

You say that you have to run both sides full tight, so to speak, to get any toe in? That is really odd. However, there isn't any such thing as a standard number of threads exposed and so on. My setup is sort of home made and the machinist who did the work just copied the lengths of the parts I gave him (one piece spring plates, like yours were, as the base) and I have plenty of toe adjustment.

An easy fix here could be to elongate the two slots in the rear of the spring plate so the banana can be moved just that little bit farther forward. Since you don't need the eccentric for adjustment, you can replace it with a bolt and some washers, and keep the fat adjuster out of the equation. I think you will still be able to deal with the camber this way. And is the jam nut on the Heim joint quite thin? That might be a way to gain some more forward movement. I'm not sure that you even need a jam (or lock) nut if your setup is just a heim screwed into a threaded hole in the spring plate equivalent end. That adjustment can't change all by itself as the plate and other clearances prevent rotation by more than a hair.

Chuck Moreland replaced a torsion tube and did a great write up on it - maybe you have found that? It is a very substantial job, and you need to cut openings into the firewall so you can get full circle welds, and then weld them back shut again so you are mucking around and weling in the passenger compartment, pulling upholstery and seats out, and so on.

Me, I'd spend the money on 935 style adjustable inner mounts and reinforcement to the tub, and switch - if you haven't already - to aluminum bananas.
