We are going to work very slowly and not try to jack up this house a

The 2 other 2x supports shouldn't need to be raised any more than the
hair that it will take to pull them out and replace them. The only part
of the floor that will need to be raised to any degree is the
center-most part, which will just be brought back to level, plus the
hair I need to slip the new support in to place.
