1 Traxxas Sledge chassis plate. It only has 7 drives on it and only has been driven at the local construction site. The ruler is on the bottom of the chassis. The chassis is bowed up in the center, also if you follow the bottom edge left you'll see a mild bump up (or dip if the chassis was right side up), that's where the motor mounts. You can't see it in the picture but the chassis is also twisted.
