There's been a lot of guys wanting to swap out the 3.9 for a 5.2 motor on a 2WD truck. There has been a lot of speculation on the motor mounts. Well here is the real deal:
The engine brackets from the 3.9 (below) will not fit the 5.2 motor.
You will need the engine brackets for the 5.2 (shown below). Hopefully your donor will have them already on. If not, take note of how the bracket bolts to the "ears" on the side of the motor. It should be on the front side of the "ears". Also, you will need the adapter bracket for the driver's side frame bracket. (shown below) This puts the mount forward and lower.
On the driver's side, the new frame bracket it is held in by 4 bolts instead of 3. The new bracket is mounted as shown below. The old triangle brackets for the frame are no longer needed.
On the passenger frame bracket, the first pic shows how the 3.9 mounts and the second pic is of the new location for the 5.2 motor. Once again, the triangle bracket is not needed. The motor mount is now bolted directly to the crossmember in the furthest forward location. Should be a dimple above the bolt hole.
This pic shows both sides mounted in the new locations. This pushes the mount forward and a little lower. Should be pretty much level and even now.

something don't look right about that mount. you might be able to bolt a magnum v8 in there with the mounts but i don't know if i would trust them. even Sixgun had to have his mounts welded because they were separating from the power that the 6 cylinder put out. steering stabilizer is most likely a bolt in kit but you should not likely need one. if you got a shake that is most likely something different.
