Thanks, Keith. The front end seems to dive fine. It does want to drive downhill on crowned roads. Other than that it is pretty smooth and steering is tight. It's the visual inspection of the springs that gave me pause.

Is the gap in the leafs something to worry about?

Does the three-leaf pack have a higher (stiffer) spring rate?

What will adding caster do? I'm not overly familiar with alignment fine-tuning.
