I know most ford van axles were a little wider than the trucks ones
I know for sure the 1/2 ton 8.8 vans where wider not sure about the 3/4.
my `69 galaxie had a 9 3/4 31 spline from the factory, I should know I rebuilt it twice. they made that axle way before 1980 and they used it in almost all the light trucks with the bigger engines. I know they were still building them in in the `80's
