1951 Model Year Transition:
The 1951 Chevrolet and GMC pickup model year was a transition period for Advance Design truck beds. Early-production trucks were equipped with a 9-board bed floor (8 bed strips), while later-production trucks received the revised 8-board bed floor (7 bed strips). Because an official GM production break has not been widely documented—and many trucks have had bed components replaced over the years—please verify your bed configuration before ordering.
How to Identify Your Bed:
An 8-board bed uses eight wooden bed planks and seven metal bed strips, while a 9-board bed uses nine wooden bed planks and eight metal bed strips. Count your bed boards or bed strips before ordering to ensure you select the correct replacement components.
