The backlash reading you took is for that set of 3.23 gears, it's meaning less to the 3.91s. There should be a pinion depth number on the head of the pinion , but you need special tools to measure it .
You can start with the shim that is on the 3.23 stem and go from there, hopefully you got a inner pinion bearing that's a TOOL if you decide to use the gear pattern as your guide, you'll ruin the new pinion bearing pulling it off. I hope you purchased a solid spacer to replace the crush sleeve, use your old crush sleeve as a guide where to start .
As far as the cone type rebuild, you can polish a turd but ....
I was just messing around in the garage. thats why I took a backlash reading. It was good practice. I should be able to check pinion depth based on the pattern, so there's no way I'm going to buy a tool to check depth. Dr. Diff doesn't even use one he said. I will use the old inner bearing and hone it out for a set-up tool. And yes, I bought a solid spacer with shims to set the pinion bearing preload.
As far as the cone type sure grip. I bought the necessary shims and will have the cones machined to rebuild the unit. Cost me $15. If you wanna hand over the few hundred bucks for a powerlock, I won't say no. It is Christmas ya know... If not, I'll use what I've got thank you very much. Cass said he's rebuilt the same unit multiple times. It's a street car, not a race car btw...
Thanks for the input. I guess at this point, there's no 'readings' I need to take. I'll just get it apart and start putting her back together.
