pick-up beds & steel

[s.e.charles]

search turned up lots of wood related threads, and the Mack Hils site shows a '31 steel bed option, but i wonder if anyone here has one.

Q: are the dividers between the wood planks still used over a strip steel body, or is what i'm seeing a stamped panel and the bolt heads are holding it to the cross sub-structure?

truck will see no bovine nor other hooved beasts (scale model tow truck w/ custom utility body)

thanks
