By late 1978, the E-Z Pack rear loader once again underwent a significant revision. The basic slide-sweep method was retained, as were the pusher cylinders that operated the sweep panel. But now, the slide and sweep panels were of more-or-less equal size, and the slide cylinders were relocated to the inside of the hopper, above and parallel to the panel.
Revised E-Z pack rear loaders now had slide cylinders (yellow highlights) mounted inside the tailgate structure
    Along with the redesign came a shuffling of model designations. The HC-300 (3 yard hopper) was replaced by the HC-250 (2.5 yard hopper) available with a 20 or 25 cubic yard body. The mid-range C-200 (2 yard hopper) could be had with a 17, 20 or 25 yard box. The nearly identical M-200 was presumably an entry level, light duty version on the C-200.
    An all-new model, the M-150 (1.5 cubic yard body) rounded out the new line as the compact model, with a choice of either a 10 or 14 yard body. The new lineup would remain in production through the 1990s, even as a new bulk packer, the Goliath, debuted in 1984. This design has also been sold around the world by various manufacturers, including USIMECA (Brazil) and McDonald-Johnston Engineering (Australia). The E-Z Pack badged models appear to have been phased out shortly after introduction of the Apollo model, a smaller version of Goliath.

After 1984, some C-series bodies remained in production, becoming mid-range companions to the new Goliath, such as this C-200D
