also...the 3.73 and 3.91 gear sets are for the 226mm Getrag differential >> not for the 215mm Mettingen (standard diff. on 'auto R/T w/o anti-spin option)

For the 'auto SRT folks ('09-'14) - your 3.06 geared diff is a 226mm Getrag (and includes anti-spin).

Nothing other than the pumpkin. Took about three hours, I believe. Dropped the cradle, and the guy helping me is very meticulous so that everything was buttoned up properly.

Of course, then there was the bug in the Trinity software where it couldn't update the gear ratio on the newer cars, but I believe that little issue has been resolved, but with an 09, you'll be fine
