I just made the discovery that the Eaton hub will work on the 14 bolt axle.
I was trying to come up with a way to use the original drum and park brakes on a 67" 14 bolt axle. I was using dually hubs and comparing brake drums. The dually hubs put everything 1/4-3/8 in too far.
Oh a whim I pulled the Eaton hubs off and low and behold they work! They put the WMS out 7/16". Right now it looks as though the original backing plates and drums will work with the 14 bolt! No fabrication needed! It will make the 14 bolt about 63.5-64" WMS, but it'll still make a good swap into an early rig.
I'll update more later.
