the "correct length" is whatever you set the adjustable uppers AND lowers to in order to achieve the caster YOU desire.
The length somebody else runs is irrelevant - only a guide. Part of setting up your jeep correctly is about setting your axle position by checking full bump, full flex and full droop with the springs removed. You set your caster/pinion angle to get what YOU want, and extend the bumpstops the necessary amount to prevent interference issues and suspension component damage.
