Most of the tanks are held on by two bolts, usually with wing nuts. In this case though, I removed the entire toilet, scrapped the old ring off the floor and bottom of the throne. All while moving a towel around because I had put it down in the pipe to prevent sewer gas from clouding the room. Then I argued with it trying to line the studs up with the holes in the flange on the bottom of the toilet. Walked away for a minute to gather my thoughts, then it dawned on me to just remove the darn tank! It was so much easier, especially since I was by myself. I just could not get the studs lined up while holding the toilet. BTW I am far from a plumber, but I'm not going to let a $4 wax ring cost me a $200 plumber service call!
