I'm trying to replace the broken rusted cast iron toilet flange in my basement. I think it's joined by lead to the drain pipe. I tried to drill through the lead join but it's really thick, about 2 inches. Also tried to torch the joint for few minutes but the lead doesn't seem to melt either. I saw some people using grinder to cut the flange and remove it piece by piece.
Can you advise what is the way to remove the flange?
Another question is the size of the toilet drain pipe. Mine looks like 3 1/2 inches (picture below) instead of 3 inches or 4 inches. Not sure I can use any of these because they are 3 inches or 4 inches:
