Converter stuck in cranksaft!

O.k. This is weird.

I just tightend the tranny to the block and the converter wouldn't move. So I unbolted the tranny, and the converter pulled out of the tranny and the converter nub was stuck in the hole of the crankshaft!
I did get the converter off, but now what? Can I sand the nub of the converter, or the inside of the crankshaft? How odd is something like this.

It is an Eagle crank, so that might have something to do with it? :angry5:

Thanks...
