You might be able to get F150, F250, or F350 seats to bolt to the van seat sliders. Most F-Series seats do not have arm rests though. I have seen some arm rests on certain F-250/350 front seats, but I do not know off hand what years they came in. I think most of the E-Series front seats will swap across bases with little to no modification.
