No this is a different dump bed... Tonka used both beds most of their dump trucks came with either or....they were interchangeable...
I got a deal on 3 dump beds...if your looking for them you can sometimes find a deal here on a "project" or parts truck, basically it's a little to rough for the collector. But they are fine for what we do with them.
