Outer Limits 4x4 Board

Hey Everyone!
Just picked up a dual transfer case for my ln106 single cab!
Was wondering if anyone if i went solid rear drive shaft what length it should be shortened to? And the same for the front but lengthining that one Cheers

measure it when you have them in, it will be different depending on 100milliongazillion things.

Lift, position of f&r diffs, drivetrain lift, etc etc etc etc.

Or work it out get the tape measure out..
