It is the same floor flange. I always make my own removal tool...disposable. I take a hardwood 1 x 2 an drill a 1/4 in hole toward one end. I insert a 1/4 in bolt thru it. Long enough to extend about 1 to 2 inches. I make another such rig which will line up with the other side of the flange holes when the first one is inserted to one hole. It will now work as a wrench.
