I can't answer your question but I have 2 links saved
that are an interesting read.
1st one has info about spider gears.
2nd one has good pictures to show what the Eaton looks like torn apart.

Hope this helps and in no way am I try to make this about a 14 bolt swap subject.
I want to run my Eaton also.
I have 3 center chunks.
One of them is an early Eaton that have one pinion bearing an a bushing in the rear of the pinion.
The other 2 have pinion bearings in front and the rear.
