Major Design Changes
1990 marked a differentiation year for GMC by introducing an Extended Wheel Base (EWB) model that llowed from an extra bench seat making a 15 passenger van. This was a differentiating factor from Dodge & Ford who only featured a welded-on body extension.
Late in the model generation GMC intrdoucd a longer nose and four head light design. This became more popular with conversion companies, primarily for school buses. GM continued to sell stripped down version for these and other conversion purposes.
