Project Upsize: Axle Swap

I am starting the process of swapping the axles in my YJ.

I am swapping my open Dana 30 HP 3.07 front axle to another Dana 30 HP already geared at 4.10 plus I will be installing a Lock-Right.

I am swapping my open Dana 35 3.07 rear axle to an open Ford 8.8 geared at 4.10.

While I am addressing various aspects of my JY axles like brake rotors and pads I am also pricing my various drive shaft options. I will consolidate my final decision here, but for now I am tracking the various options here.

Solid axle shafts from a TJ or XJ ($100)
