Lots of info here and now I really have to consider this from all angles so I'm gonna need some education.
From Hotrod Lincoln's post it looks like the later model 16's are not the same as the earlier factory 16" split rim. And the 16.5" rims may not work either.
So now I'm wondering if the original split rims may just be the best choice. Either that or swap the entire rear end for the mid 70's dually rear. The rear end swap would probably get into some spring location and drive shaft issues that I'm not equipped to deal with.
