Im getting a little over my head on this job. I've never done this before. Im trying to help this guy change the ring gear on his 24. I'm told the wrench number is 5Z210. We got the engine out and now I'm lining up the right tools to do the job.
I've found a socket like this http://www.grainger.com/product/PROTO-Flex-Socket-4TDF4?functionCode=P2IDP2PCP work very well if you don't have access to the Ford tool. I think the size for the flywheel bolts is 11/16 inch but please check. You can probably find one for much less, but a quick web search put me to the Grainger site. I have a full set of these from Bonney that I purchased over 40 years ago. They come in very handy in tight places.
Common Ford wrench M - 01A -17017 B
Grind down about 1/2 of the small end to fit on to the flywheel bolt.
This is the Blackhawk flywheel wrench that works very well. No grinding. Ready to use.
I sold one of those at the Petit Jean swap meet last week. Anyone who works on Model T engines needs one.
I have not been able to find an old time wrench to do the job, so I heated a modern ring spanner and bent it to give enough angle to crank it. It does have a thinner head and this gives clearer access to the bolt heads.
Hope this helps.

You can use an old 11/16 box end and bend it by trial and error to get the correct angle.
I have the 5Z tool but find that a modern 1/2" drive 24" long breaker bar with a 3/4" socket works better.
Royce -- I hope you're not tightening those bolts using a 3/4" socket.
Sorry, should be 11/16"........
