The bracket is the same bracket that *should* be used to attach the
normal guys. With my 45G the only difference is the hardware that goes
into the ends of the brackets.
At each tower leg there is a shorter bracket that runs between the outer
pieces, but goes on the inside of the tower leg. These things are well
mounted and take the stress of the guys off the individual tower legs.
If you have a large wind load and the tower base is in concrete it
greatly reduces to torque down through the tower to the base. With the
tower set on a pier pin it reduced to pull due to rotation on each guy
line which again can be considerable when figuring the leverage between
the tower center and legs. The longer torque arms reduce this
substantially. OTOH most installations don't come near needing them.

You're missing some parts. The short pieces that go inside the tower
between those outside brackets. Look at the drawing of the bracket in
the ROHN catalog. it should show that angle bracket.
