You guys are right, but you should also compare housing strength. If you are swapping a V6 diff for the extra strength, you could also swap a 93+ LC factory locking or aftermarket locking diff f/r into the factory 76 axles for upgraded bearings and spline count. Of course all of this is really just about what you want. 4thewkn wants a GM motor, so mini axles are simply another choice and maybe a good one for his needs. My preferences are different. I am going to start on my 4Runner next, and that one will be much more modified than my Cruiser. I look forward to watching the build on this Family Cruiser!
