Simplistically the term Crossover, XO, refers to a period in 1972 when some vans were built with the new square rear lights and squarer air intakes, but they retained the low front lights and wrap-around front bumper. The larger rear was designed to take the optional 1700 type 4 / pancake / suitcase engine. Further less noticeable differences include flared arches, fixed rear apron/valance, late type engine support, flared arches amongst many others.
