After working on this as time allowed, I finally got it off.
Heat and hammer didn't quite get it done. It took heat and leverage to do it. I heated the angle gear coupling around the rim and inserted an old, bent bolt in one of the unthreaded holes. There is a rectangular-ish bump on the angle gear housing on the passenger side which I was able to use to as a leverage point for a pry bar to push on the bent bolt, pushing out the prop shaft behind it.
Not an easy or a fun job but patience paid off. Thanks to all who shared their knowledge.
