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?
