Just picked up the cable car and impressed EXCEPT where those trucks were located (large nut and screws), just looked butt ugly. So unscrewed the cable holders/racks at each car end, and re-positioned them so the rack ends cover the truck nuts. Can reuse two screws to secure the the holder/racks. In addition add a thin bead of elmers glue along edges to help hold them in place (in case you wanted to remove them later). Add some crates or tool boxes to fill the now vacated spaces. Paint over the shiny sliver screws to blend them in.
Maybe Menards should redesign this car slightly to cover those truck nuts.
Pictures later.
