IMHO, a mechanic capable of gear setup would know that the bearing sets and
housings are the same regardless of gear ratio.

Correct. The cutoff is between 3.31 and 3.54 for the DANA 35. The higher
the numerical ratio the thicker the ring gear and therefore the mounting
flange on the carrier varies to compensate.

Again, no insult intended.
All that said, I have yet to attempt setting up my own gears, I have them
done by professionals.

That is correct. One thing that you will learn if you associate with
Chrysler Products for long, is that they just have to be different.

By the way, if you do this, many people recommend new ring gear bolts, and
high strength thread locker on them.

Re: Differential gear change question
Richard,
All the information you need to set up a differential is in the factory
service manual.
As an experienced Engineer you have the knowledge to complete the labor and
list of specialty required tools is in the back of each manual section and
drawing showing the tools in use..
Examples below:
http://i112.photobucket.com/albums/n...ance/tools.jpg
http://i112.photobucket.com/albums/n...ce/tooluse.jpg
Just get yourself a manual, order the parts, assemble the tools, and get to
work...
