There were some minor cosmetic changes, but the most significant change was under the bonnet in the guise of the new 2.25 - litre diesel engine . Body configurations available from the factory ranged from short - wheelbase soft - top to the top - of - the - line five - door station wagon . In 1967 a 2.6 - litre inline six cylinder petrol engine was introduced for the long - wheelbase models, which also had servo - assisted brakes . 811 of these were NADA (or North American Dollar Area) trucks, which were the only long - wheelbase models made for the American and Canadian markets . </P> <P> From February 1969 (home market), the headlamps moved into the wings on all models, and the sill panels were redesigned to be shallower a few months afterwards . </P>
