I'll try again...
Comparing the new base (yours) to the old base (mine), I'm wondering how
different they are.
The old rebar cage is a simple affair consisting of a bunch of straight
pieces tied together. There are no bends.
The hole is 3'6" X 3'6" X 6'6" deep which appears minimal to me.
There are no bolts holding the base ears. They are welded to #10 (inch
and a quarter) 60" long rerod that extends to the top of the ears. #3
rerod extends them to within 6" of the bottom of the hole. It does not
give the latitude you have with two bolts holding each ear. It's a
strong set up, but appears much more primitive than your LM470 base
