Some have asked what was the final outcome of the -66 steering wheel being off 90 points after the new tie rod ends and idler arm were installed. I told the brake shop to have the steering box rebuilt and get the wheel straight up and he did. Turned out a previous owner had swapped a different box and the steering shaft was not centered to the box correctly. That is his story anyhow but it steers much better, most of the slack is gone, and the steering wheel is back where it belongs rotationalwise. Case closed.
