Ridetech spindle instal

[ricer]

so i finally got around to installing the spindles and i can spin the castle nut to just barely finger tight while not being so low on the ball joint that the cotter pin won't be within the nut.

Has anyone ever had to add washers/shims/etc to the ball joint to be able to get the appropriate torque on the castle nut while still being able to have the cotter pin nested inside the nut? I am thinking 1-2 possibly 3 flat washers should do the trick but just wanted outside opinions as well.
