 There is hardly any in the crown gear/pinion, but there seems to be 
 quite a bit (.010"? hard to measure) in the bevel gears inside the 
 diff.  I can hold the diff input still and freely rotate each hub on 
 the rear end about 1/16"; in other words, there's about 1/16" of play 
 in the hub rotation. >>

Dan,
I ran into a very similar problem with my TR3A.  I bought replacement thrust 
washers  from TRF.   The differential side gear thrust washers didn't need to 
be replaced.  The differential pinion gear thrust washers (look like belville 
washers) were available in various oversizes.  I think TRF had them listed 
under TR6 where they're "official" replacement parts.  You can also get them 
from VB or Moss.  I picked up a range of sizes and kept trying thicker 
washers until I was comfortable with how tight the diff was.  I still have 
the parts I didn't use if you're interested.
