[TowerTalk] Wind area for Rohn tower sections

[W7CE]

I've looked through the Rohn catalog but can't find the effective wind area 
data for Rohn tower sections.  I'd like data for 25G, 45G, 55G and 65G, 
although my immediate need is for 65G and 25G, in that order.  I can use 
either the total area for a 10' or 20' section or the area per lineal ft of 
tower section.  Does anyone have this data or know where I can find it?
