You are right about the Getrag. A whole list of things to get along with the larger 226mm axles. You can get the open 3.06 diff from a 2011 to 2014 and it will bolt right up. However, you will need a tuner to program the TCM for the new 3.06 diff. Hit and miss with Diablo. It seems to work for some and not so for others. If it does not work you will need to send in your TCM to get it programmed. Less and less people have reported problems lately though so maybe the new software updates are working better than in the past.

If you do the swap make sure you get new axles seals (Close to the differential) when you do the install.
