Kirk's already installed the 5.29 gears for the Gen II's. These ONLY fit the small front diff, so I guess that confirms the fact that all 3.0/auto Gen II's used the small front diff.

I also confirmed this in WINCAPS. I compared the front carrier and the 3.0/auto's use the small diff, which is shared with the 2.6l trucks and the 2.6l Gen I's. The front carrier on the 3.0/MT trucks is shared with the 3.5l Gen II's, the 3.0l trucks, the 3.0l Gen 1's, the Sports, and the Gen III's.
