And of course with all rework, it seems that something will go wrong. And it did.

There are about 60 screws holding the tank to the spar and leading edge skin. I buggered up the head of one of them and could not get it to come out.  I had to use one of my screw removal bits to get at it, and after a lot of effort it came out.  With the tank out, it was a trivial effort to get the new bolt in and torqued.  In picture number three the wing is in the cradle with about 20 pounds of weights at the outboard end to keep it from tipping up on that end.
