CMP chassis

[cletrac (RIP)]

Here's a comparison of a C8 frame (on the right) and a civilian 1/2 ton frame. The frames are basically the same from the front to the crossmember at the u-joint and from there back the C8 goes straight back while the half ton keeps getting wider. This is because the half ton has the springs under the frame rails and the C8 has them outside the rails. The spring mounts on the rear ends are the same distance apart, but the half ton rear end is wider between the brake backing plates. The C8 uses the heavier 2 ton steering components. The positioning of the motor and crossmembers in relation to the front axle is the same on both frames.
