Well thankfully I was right the flex plate bolts were ALL loose some worse then others. Since I had the starter out I went ahead and tightened down from there after a drop of thread locker. Then marked each bolt with a spot of paint so I can inspect movement later.
Started the car and listened and it was all gone. The starter is still grinding a little but I am going to troll the junkyard tomorrow and see if I can find a spare.
Thank you guys for allowing me to bounce these ideas and your responses. It is always helpfully to hear others ideas.
