The 3/4 Scale Wrecker featured a custom-built wrecker body that was specifically designed for recovery and towing operations. Fabricated mostly of wood for the exterior panels, bead board, and painted wood panels make up the body. A traditional C-cab covers the passengers and is decorated with brass handles along with gold pinstriping throughout the body. The "3/4 Scale" designation indicated that the Mack AC Wrecker was smaller in size compared to the standard Mack AC model. This reduced scale allowed for increased maneuverability and easier access to tight spaces, making it suitable for navigating congested urban areas.
