Difference in engines between Rubis and non Rubis?

Hey guys,
I'm looking at trying to buy a JK Rubicon where the engine doesn't work and then find another JK Rubi if possible but its going to be easier to find a non Rubi that has been rear ended and get it for cheap then swap the engines. I would assume that the engines are the same but I'm trying to figure out if there are any issues i would run into? Like maybe with the swaybar disconnect components/ wiring harnesses or the locking axle components/wiring etc. If anyone know of any problems that would arise please let me know. I plan on trying to get 2 JK's of the same year but again that limits my choices. Also if the bad engine is a 3.6 I would make sure the good engine is a 3.6 , same for the 3.8. I'm open to all comments and ideas.
Just trying to get another JK on the road.....and soon the trails
Thanks Guys!!

What about transmissions? I've read manuals have longer driveshafts.

Not sure about all years, but for the 08, the drive shafts are the same between manual and auto. There is a tail shaft spacer in the auto that makes it that way.

Why dont you just pick up a used motor. Lots of hemi's going into jeeps and there is ample supply of good used 3.8 motors.

If you learned something new today, you had a good day.

The JK rear shafts are all the same length from 07-11, given 2 door or 4 door remains the same. The only difference there was the Rubi's had a different transfer case and of course the axles. The sway bar disconnect isn't an issue since its just a box mounted to the bar itself. If you need an engine all JK's from 07-11 will work fine.
