I know just what to pull it with....

A ham friend [long dead] was friends with a rather famous ham, Sam Harris
[W1FZJ] who went on to do multiple firsts. Sandy needed a tower pulled
out; and Sam said he'd found the right tool in the weeds along the road.

It was a streetcar jack..... and the tower was no challenge.

I agree the blocks lined with tube approach. I'd glue the rubber
in.

But I'd suggest you use bolts sized so you could use a air rachet or
small impact wrench to install remove the bolts. If wood; weld the
needed nut to a scrap so you can screw it to the wood. That way it's
a 2 hand, not 3 hand, job.
