I think you are right. That is also what my '06 Cummins has in it (actually, I think the front and rear are both AAM). I don't know how similar they are to the GM version, but I bet they are close. Does anyone know how the AAM compares to the 14FF for wheeling? So far all I have heard is that there aren't many options if you want to change your gear ratio. I have done a little research but would love some more info.
