For 1972, the Saf-T-Liner body underwent a major redesign. Along with extending the rub rails completely around the body, the front and rear roof caps were flattened (to accommodate 8-lamp warning systems), and the windshield was enlarged. Following the addition of safety upgrades to comply with safety mandates in 1977, the Saf-T-Liner body saw use in the Conventional through the end of 2006; in modified form, it remains in use with the EFX and HDX (and resized to fit the Minotour). At the smaller end of the size scale, the Saf-T-Liner body was resized to produce the Mighty Mite, a narrow-body school bus on a shorter-wheelbase conventional chassis.
