I honestly have no idea what the caster is. You mentioned that the spindles looked laid back. I did have the alignment shims on the wrong side of the A arms so I moved them to the front of the A arms. One step closer. =)
This little video probably will answer many questions about if the A arms are on correctly as well as shows at what point the steering arms hit the LCA's.

I know, it's not under full load but also not at full droop. I really appreciate your time helping me work this out.
