If the tower and problem was mine, I would:
Rust proof the crack (cold galvanizing spray) to prevent any future corrosion.
1. Put bunch of hose clamps close to each other over the length of crack.
This would keep the tubing from "opening up".
I would put couple of hose clamps on the section of the leg between the tower
cross braces as a spacers for thickness. Worms should be facing more-less one
way.
2. Then I would clamp piece of angle iron, length of the tubing between the
braces and put bunch of hose clamps, close to the clamps in step one.
It might be ugly, but should be stronger than other "unrepaired" legs.
Another way is to weld or braze the crack. More elegant way, requires welder
and a skill.
Otherwise do as manufacturer says :-)
