Re: How much "slop" in the driveline is normal?
If you put the e-brake on, place the trans in neutral there should a SLIGHT
amount of "backlash", or play as you twisyt the driveshaft. It will feel
like a lot, but in reality it's only about .010" at the ring & pinion. Now,
if you add lockers to the equation, then there's an additional amount of
"take up" in the side gears. However, you should be able to feel the small
amount of play between the pinion and ring gears.
If in doubt, compare it to another similar vehicle.

Thanks Mike,
I was thinking of that too and will take a close look at the tranny and
engine mounts.
Also, thanks to all the other replies to my question. I will certainly post
a follow up to anything I figure out..

Re: How much "slop" in the driveline is normal?
You are correct!
Where shall I send the cookie? ;-)
So, the LSD (I have the original equipment D44 rear w/trac-loc)
tightens up the possible play in that rear diff, huh?
