This is what a 14 bolt swap takes.
It’s very likely that you could use modern drum brakes from a 14 bolt on your original Eaton, as yet another option. I haven’t researched this enough to know just what’s required, but I’d bet it’s possible and not terribly difficult.

I used to use the later model drums on these by having the holes in the hub drilled out to take the larger size studs.
