Some alignment help needed please.

To get more caster you want to move the upper ball joint to the rear. This is done by adjusting the upper front eccentric, for out, and the rear eccentric for in. Then move the rear eccentric out enough to set the camber. I use zero camber, because the more negative results in less caster. To get more, you need to use offset bushings. I have had luck measuring center of rear axle to center if front hub, with wheels straight ahead, to check for equal caster. Checking how car drives is also a good indication. Lack of neutral behavior when driving straight down the road is an indication of an alignment problem. There should be a very very slight tendency, to the right without steering input.

The A-body is a great handling car, when properly adjusted, do not accept compromise. It just takes time. The setting are interrelated, so recheck toe-in and make adjustment to insure steering is always centered.
