Drawing of replacement access cover.

Dimensions provided to make a new plate with drilled and countersunk holes.

Five skid strips were used in the first series "four stake pocket" bed (not not counting the side angled strips). This meant that six "boards" were used to cover the floor, each gap between adjoining "boards" was covered by a skid strip.

However, the "boards" were not necessarily all one of continuous width but, more often than not on these early beds, each "board" was made up of two or more individual narrower boards laid side by side. It is not clear from a bed such as this that has seen a lot of use, but these individual narrow boards could have been originally glued together. They may not have been glued as they were quarter sawn so cupping was not an issue.

Note how the individual narrow boards do not necessarily lay parallel to the evenly spaced and parallel skid strips. Some are not even of uniform width but rather cut at taper.
