    You didn't mention the rotator but I'll assume  it's a HAM IV or 
TailTwister. I've never worried about shimming them unless  there was some bind in the 
system. 
 
    The rotator  plate/mast/thrust-bearing/bushing/taper-top/whatever system 
is not precise so  you probably don't have to worry about it. Nonetheless the 
previous responses  suggesting shim stock or other options are all good ones.
