When you bought a 1936 Chevrolet 1 ½ ton short or long bed truck, they all came with a round hole in the center of the rear cross sill. This allowed the dealer to easily add a tow ring with threaded attaching rod. This rod was simple inserted in the hole with a nut and washer securing it to the center of the cross sill. This extra allowed for a quick connection when the 1936 was needed to tow a disabled vehicle. test Rear View test Side View
