    Once you have swapped pinion yokes, yes.

    Do the 05-06 still run the little 2 piece driveshaft like our 04s?

    I am not sure about that as I have never had to swap driveshafts. I had an 06 rear installed in mine last summer so I could have the original 04 rear rebuilt. Might work though if the output shaft in your trans is the same as the 04.

    Stock gears. The original rear went on my way home from upstate NY two years ago. Howled like a mofo.
