Axle code help

I reviewed the various decoder websites but cannot seem to find anything for the code 0A. Maybe I’m reading it wrong. I’ve attached a picture for help.

No, you're not reading it wrong, unless I'm reading it wrong too.
I don't find anything in the Ford Master Parts Catalog on "0A".
I thought maybe it should be 04 but that code wasn't used in '77.

Thanks. I've googled all I can google. Next time I visit the truck, I'll take some pictures and see what I have the old school way by counting turns.

If you're lucky, the rear will still have the factory tag on one of the retaining nuts. If it's there, you can use that to decode, it uses a different coding system than the door warranty tag.
This is the Ford 9" which is probably what yours has. However, in 1977, Ford put the Dana 44 in some trucks. If that's the case on your truck, it will have a removable rear cover and the ID tag will be bolted to that.
