[TowerTalk] Rohn 45 Bearing Plate

[rfman45]

I am using Rohn 45 and want to put a second thrust bearing between the rotator and mast. The bearing plate p/n BPL45G can only be mounted at the top. Is there any way of putting a second bearing plate between the rotator and the the top baring plate?
 
Thanks in advance!
