Back at the second last GSL (2017?), Andy Martin was selling his transkit to convert a Tamiya Mini kit into a pickup. The kit was well packaged and the pieces are excellently cast, however, no instructions are included. Has anyone built this transkit or have it in their stash. Most pieces are self explanatory (body, chassis plate, grille). I'm just curious about the bottom three pieces in the last picture. I looked through a set of instructions to a Tamiya Mini kit, with no luck in identifying them.
