FWIW, later production G-1000s include a sheet in the instruction manual 
telling how to sequence the tightening of the various bolts to avoid 
putting a bending stress on the cast aluminum clamps, which is what kills 
them.  In a nutshell, you need to be sure the clamps are tight on the mast, 
then make sure they are concentric with the top of the rotator before you 
tighten the bolts that tie them to the rotator, and finally tighten the 
rotator mounting bolts on the rotator shelf.

A big plus for the Yaesus, in my opinion, is that there's no need for shims 
regardless of the diameter of the mast (within the range of the clamps, of 
course).
