replace basement main drain

[NewTerry2024]

Hello, everyone! I am replacing the main drain clay pipe in a 50+ bungalow with ABS. My plan was to saw off the end and add an adapter from clay to ABS pipe. But there is a concrete pad beneath the clay pipe and I cannot saw through. I even damaged the end now. Now I have to see what's up there for a new opportunity to make the connection. I don't recognize what's up there: two cleanouts in a row?
