07 Rear Pinion Bearings 8.4" diff vs 8"

I have truetrac ready to install in my 8.4 and would like to replace the pinon bearings while everything is apart, I'm also installing a solid spacer. What are the part numbers I need for rear inner and rear outer pinion bearings for the 8.4? Are the pinion bearings interchangeable with the 2nd gen 8" rear diff? (I'm aware of the other differences). So far I have found options for the rear inner bearing/race but nothing for the rear outer for the 8.4" so I'm thinking they are interchangeable but I want to confirm before ordering any parts. I found these diagrams showing the same reference part numbers but after looking up the numbers (41201B and 41201A) its still not completely clear.
