Detroit Truetrac Set Up Problem???
When installing the Truetrac this weekend on my 03 I ran into an issue. I just swapped the G80 for the new Truetrac, swapped new bearings, torqued everything to spec and checked the backlash (between .003-.005). When the main caps are loose the backlash is within .003-.005 all the way around the ring gear. When the caps are torqued to spec there is a tight spot for about 40 degrees and the other 320 are free. The tight spot is noticeable by hand and the tolerance is tighter .002-.003.
I've thought it could be the ring gear not fully seated (maybe i missed a bur or flaw), or bad new bearings. Anyone have this issue happen before?

It sounds like there could be debris under the ring gear. In order to check it properly it needs to have both caps tightened down.
You could remove the ring gear and install the truetrac. Put a dial indicator on the machined surface where the gear is mounted and turn it over to make sure it is true.

Yes, I believe there are members in the 10's with built 10 bolts. I think it was dirt track racer 81. Yep, here's a quote from him:
That's from this thread:

I put a truetrac into a 95 14 bolt and I just used the bearings that came in the install kit from Yukon. I'm 95% sure they're the same as the stock bearings, the kit is specific to your entire diff not just the carrier you put in it.
