Vans were a big thing in the Seventies but what if they gained popularity a decade or so earlier? Given the lack of pollutions controls and insurance penalties there could have been muscle versions vans for each of the big three. For example a Plymouth Vanacuda has a nice ring to it.

The Ford version is maybe a little less successful of conversion. Stangvan?
If you will excuse mixing and matching of eras the Mustang II grill fits a little better along with some other custom touches. What van would combination would you like to have seen?
