I have a 2002 4x4 6 speed
Somebody put a 12 valve front end under it like 98 back I'm missing the driveshaft for one but my main concern is the lines for the actuator are mia and the little plug the plugs in the side is gone and I cant seem to run it down does anyone know where it originates at and does anyone know if there is a difference in the 98 back front ends?

There is a huge difference in how the brakes mount, probably abs sensors also.

The only real benefit you have is a bettrr balljoint setup.

The 02 axle makes for an easy swap to larger brakes using 3rd gen parts.

The vacuum line layout should be the same. i used a 12v vacuum line diagram to replace my vacuum lines on my 2001. theres
diagrams floating on the internet of the vacuum layout

Did the 01 have the vacuum operated CAD. If so get a diagram and replace all vacuum lines missing. If not get a cable control kit for the CAD an install it. Do not know what "Plugs" you are referring to.
