If you're thinking of the TX-455, which is their smallest 55' tower, the
2.75 yards of concrete would normally be enough, but only with the standard
base embedded in a monolithic pour.  Drilling for j-bolts or whatever is a
bit risky, the pour obviously won't be monolithic and you may damage the
existing structure.  I'd probably dig a different hole and start again, with
the U.S. tower base.  You can use the existing concrete as a base for a nice
barbecue!  -WB2WIK/6
