Clay.
I have a Rohn 65 tower (150') The section mounting plates are as specified in
the Rohn drawings C630665Rh 1973. It has three revisions 78/80/82 none were
for mounting plate dimension change.
the flanges are 5/8 thick 4 1/2 sq. with the 4 5/8 holes 1 1/2" off center
line + 3" sq. bolt pattern.
I have seen bearing plate made from 1/2 aluminum or modified plate steel
beacon plate.
I modified a 65 TG 10' tapered base section as the top section
YMMV
