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.
