I think I found the pinion bearing through one of the NOS parts suppliers listed in the Links page. The carrier bearings I bought new if my memory serves me, through Applied Industrial Technologies.

My truck originally had the 6.17 gear set. It's still sitting on a shelf somewhere in my shed. I swapped it out when I bought the 5.43 set.
