Don,
It's a piece of cake!! Measure the inside diameter of the cast iron pipe. It probably is 4". Go to a plumbing supply house (Noland, Ferguson Enterprise, Steinhouse, etc.) and ask for a PVC flange that slips inside the pipe and has a rubber gasket that expands inside the pipe when you tighten the bolts. Go ahead and put down your finished floor, tightly against the outside of the cast-iron pipe and allow the flange to be on top of the finished floor. Then drill 4 ea. holes in the concrete (thru the holes in the flange) and use "Tapcon" masonry screws to anchor the flange to the floor.
Best regards,
Charles
