1951 Model Year Transition:
The 1951 Chevrolet and GMC 3100 pickup model year was a transition period for Advance Design truck beds. Early-production trucks were equipped with a 9-board bed floor, while later-production trucks received the revised 8-board bed floor. Because an official GM production break has not been widely documented—and many trucks have had bed components replaced over the years—please verify whether your truck is equipped with an 8-board or 9-board bed before ordering.

How to Identify Your Bed:
An 8-board bed uses eight wooden bed planks, while a 9-board bed uses nine wooden bed planks. Count the bed boards on your truck before ordering to ensure you select the correct replacement components.
