Technical Upper Control Arm Question

I have done many alignments on old cars (does not make me an expert)
Does the car have power steering?
Most cars from that had manual steering set caster at 0
I would like 0 camber. 0/+1/2 caster on manual steering and closer to +3 on power steering cars.
Get the most caster you can and test drive it might be find without having to do a lot of work
Do you know what the original specs are?
