Update:
I got out the dremel and ground down the box. I ran a tap through the hole to make sure the threads were good. The hole was a little too far back for the #5 box, with its "lip," but I had some rounded boxes.
It was too low, but an off set #27 is right on the money:
On the other forum someone suggested a #28, and that might work in the metal box, but this seems to be fine.
