Pitman Arm Length vs Spindle Arm Length?

[SquidBonez]

Curious as to how long to make the arms on my spindles for a good balance of steering angle/leverage. My setup is a 3(?)" pitman arm going to a double sided lever that has tie rod holes 2" from center on each side (see pic below). How long should I make my spindle arm?

I have heard the rule of thumb of anywhere from 2:1 to 3:1. Your guess is as good as anybody’s.

No idea. Could make the pitman arm with several holes to get a better idea of what works better.
