Steve I think these towers haven't been manufactured for 20 or more years.
Back that far wind load documentation was not required for most ham
installations. I've been dealing with E-Z Way towers for a long time and
I've never seen any of that kind of documentation on any of their towers,
except what was in their catalogs. Having said that it may be that someone
will have something, but after having dealt with about 20 of them I've never
seen any.
I guess you could hire an engineer to do the calculations but that may cost
more than the tower is worth.
