ROHN makes a guy bracket that fits around the tower. They consist of 3 
bars about 1/4" thick and around an inch or inch and a quarter wide for 
the 25G. They are bigger for the 45G.  These sections are held together 
by some substantial bolts with a bushing over them (on the 45). The guy 
thimble fits over these, or there is a heavy duty link (looks like a 
single chain link) than can go from the bushing to the thimble.  These 
have the advantage of removing the side pull of the guy on the tower as 
the bracket takes the side loads from the guys. Of course the vertical 
load still translates to the tower.

I'm not so sure if guying off the top plate is permissible, but if so, 
then a ( safety wired) clevis through the guy wire spindle would be the 
proper connection. In his case there should at least be a safety wire as 
strong as the guy through all of those links from the guy thimble to the 
top plate.  The same is true for turnbuckles. They should have a safety 
cable around them so if they come apart the only thing that happens is 
the guy tension slacks off a bit.
