I've seen this move. In fact, I'm starring in it right now.

Remove the starter. Stick your finger in the hole and feel the teeth on 
the flywheel. If they are chewed up, we'll send a film crew over at 10 
tomorrow. ;-)

We had the same thing happen. The ring gear had lost three teeth and was 
chewed up elsewhere. The good news is that it's a $25 part from Moss. 
The bad news is that you get to pull the engine to get to it. Yes, a 
machine shop should be able to replace the ring gear. We found a place 
south of here that specialized in flywheels, and had it replaced in 20 
minutes for $45. They also resurfaced the flywheel. You should be able 
to find someone who can do this job, but you'll probably have to present 
them with the flywheel and ring gear.

We were planning to replace the transmission anyway, so this is mostly 
an inconvenience. But, it's still a big job. A pencil, index cards, and 
a box of sandwich bags are your friend.

FWIW Car Quest carries a rebuilt starter for a reasonable price.

Good luck,
Dave Ambrose

Battery pretty much dead, we bump started it and got it home. Charged the battery over night, and this morning, tried starting it. The starter spun but did not engage, great.   I pulled the battery and went and got a new one. I had a group 26R in it, but decided to get the ‘proper’ group 24. I think that was a mistake. It fits, but with no room for error. And I had an error, my mounting bracket for the battery had threaded rods that were just too short for the group 24. Back to the store for longer rods.
