I have found the following (two) alignment settings work the best for the ‘64 type front end.
Steering type: Caster Camber Toe
Manual steering: - 1/4 to 3/8 + 1/8 3/16
Power steering: + 3/16 to 7/16 + 1/8 3/16
Manual steering – Setting caster on the negative side of 0 helps the car to turn during slow or stopped turns. The higher you set the negative setting the easier or lighter the steering will feel during driving. If the setting is to high (-) the car will have a wandering feeling. I have mine set at - ½ and it does wander, but is easier to turn. - 1/4 to 5/16 is probably a good setting to start with to see how it feels.
Power steering – Caster should be set to the positive side of 0 for better road feel. The higher (+) setting will give better road feel, but to high can affect tire wear. My current setting is + 1/8 and the steering stills feels to light.
Hope this info give you some ideas for your alignment settings.
