Unable to find a toilet flange that fits a pipe with 4" outer diameter and 3.5" inner diameter, creating a blockage in flooring installation.

No simple way to identify a flange that fits non-standard pipe dimensions; standard sizes (4" inside or 3") don't work, and online or local store selection is insufficient.
