on my 38 plymouth coupe, i used a VW bug setup above the windshield. i had to modify the linkage to fit the original vacuum wiper hole spacing, but it was very easy to do. my windshield was a flat, one piece fixed setup.
i don't know how hard that VW setup would be to obtain today.
speaking of minivan wipers, look at some of the small cars or crossovers. i have seen several that had such a small sweep, i wondered why they even bothered to install a wiper.
sorry i don't recall what models or makes they were.
