1950 TRUCK BEDS CHANGED MID YEAR. 

1950 EARLY Series: still had steel floor, curved stake pockets and embossed bed sides.

        Many of the 50-Early bed pieces fit back to 42.

1950 LATE Series: had new wood floor, rectangular stake pockets and smooth bed sides (no embossing).

        Many of 50-Late bed pieces continued to fit Flare-side beds through 53-6 series and beyond.

If in doubt please ask for assistance.
