I have been using Rohn 65g for many years and I have never heard of the
flange problem you described. I find it difficult to believe that Rohn
would change their design making it incompatible with previously made
sections. Perhaps it is a 65 clone that has a different bolt pattern?

I have Rohn 65G sections that I plan to put up and have a question about the
bolt flange plates. Someone told me (K0XG I think) that there are two
versions of Rohn 65G and the flange plates (and corresponding bolt hole
locations) are oriented differently on the two versions. Does anyone here
know for sure if this is true or not? I have a lead on a used custom thrust
bearing top plate but don't want to find out after the fact that the holes
are drilled wrong.
Thanks,
Clay W7CE
