Attached some pictures from the axle swap.
I used a XJ Cherokee axle with 3.07 gears to match my own. They were used in the 4.0 with 5sp. manual.
I made a wooden Jig on the old D35 axle to get the right position for the shock mounts
The reference point is the center hole in the spring perches.
I grinded the 8.25 mounts off and made the to fit the jig.
The mounts were tack welded in the jig, and welding was finished with the jig removed.
The last picture shows the "new" drive shaft: 1" shortened, straightened, balanced, new U-joints.
