That's some good info there sideview.

Some info I saw on DWEB, someone made the change for the same reason as you. His mechanic recommended this; said it was an upgrade for the DII and stock on the Durango. The Durango (year of ?) uses a drive shaft compatible with the DII, with the 1310 u-joints. So maybe changing out the t-case front flange and installing the Durango shaft would give you something along the lines of GBR/Tom Woods quality for less.

there was no follow-up.
