Jim's thoughts are the same as mine. Has anyone here purchased new tower sections & if so, what size hardware did it come with? I suspect that the larger hole is for alignment.

My idea, not fact.  In assembly to align the mismatch of the two members being 
bolted a tapered drift pin is used in the large hole to make for perfect 
alignment.  The smaller bolt is then inserted in it's hole and tightened.  The 
small bolt then holds the assembly in correct alignment for the large and 
necessary bolt to be inserted and be torqued to specification.
Why not use two large bolts?  Well to contain costs and only one bolt is 
necessary and further there may not be enough metal in the tower leg to allow 
for two bolts.  (two large bolts mean bolts too close to the edge of the metal 
etc, etc.
