Is this a step-side or fleet-side box?
.
.,
I remember fleet-side box with wood up to 70.Not absolutely sure about the step-side boxes.They were virtually unchanged from 552nd series up into the mid 70`s.

1987 was the last year that the step side boxes had wood floors. (The bed went pretty much unchanged from 1954 through 1987)

I may be wrong, but I thought 1972 was the last year for wood floors in the FleetSide
