Both axles came from an
81 Jeep Grand Wagoneer. The rear is a Model 20 and the front is a D44.
The FSJ 20s are not the same as the CJ 20s. The FSJ 20s come with one piece
axles and bigger axle tubes. The weakness on the 20 is the possibility
of bending/flexing or twisting the axle tubes. I addressed this with my over the top
truss and tied it into the pumkin. I'm installing 4.88 gears, welding the
rear, and putting a lockright in the front.
