Put the thrust bearing on a 45AG4 top section; the holes are already there
for that purpose.
Use a second bearing on a redrilled rotator shelf where the rotator would
normally go and put the rotator at the bottom of the section if you have a
large array. I do this even on 25G for a large stack of VHF yagis. It saves
thrust bearings and rotators as well as makes removing them or dropping the
mast a lot easier.
