That's exactly what I was thinking, Gerald.

I may have missed it, but one very important factor is how deep are the holes and how deep are they supposed to be? If not deep enough the clearance becomes a lesser problem.

As far as threaded bushings, they are very easy to make if you have a lathe of sufficient size. Threads can be tapped, cut, or rolled, For a deep bushing, it's probably easiest to cut the threads. Rolled are the strongest and smoothest, but not for a low timer.

Marvin's greatest constraint is an oversized hole. I would make a trip to a machine shop with some appropriate sized anchor bolts and and have the upper threaded portion necked-down!

How about larger anchor bolts with upper six inches or so machined to fit
the base holes?
  Could the base holes be reamed to a larger size?
