After a Youtube search, I found that the holes in the top of the flywheel are basically self tapping.
I used my steering wheel gear puller, and the flywheel came right off.
The key was sheared, so I'm sure that was the original problem.
So, tomorrow, I'll get a 1/8" by 1/2" half moon key and put it back together.
I'll keep you posted.
Thanks for all of your input,
Gary
