Well, it's out... I didn't think I did much with the sawzall blades as they all went dull on me. I think that was from cutting into the cast iron. The threads have some cuts in them however some pipe dope should take care of it. Wire brush and the 2" male threads into it. Just need to get the 1 1/2" brass clean out remnants and I should be good to put the new PVC in. I do need to dry out the trap and vacuum the metal that fell in. Maybe a magnet? Got a metal strap and concrete anchors to hold the PVC vertical.

Thanks for the ideas and inspiration...

Good news. Stuff like this is so frustrating but rewarding with money left in the pocket at the end of the day.
