1 1/16thI welded a bolt head to a nut, not sure if it was an exact 27mm but close enough, something like a 7/8" or 1" bolt (so 20mm or 22mm diameter bolt maybe?)...
OP, I would just remove that lower steering shaft with the swivels on it and when it is off, check for looseness, especially in the lower joint, seems to be the common culprit.
