Here are my sideboards. I plan to add a top to enclose them so that my dogs can ride in back when necessary. Some J-bolts will keep it secured when I make it. The covered top will keep the dogs shaded and out of the weather a bit more while keeping them contained as I drive. Just not enough room to put all four dogs up front in the passenger seat.

Not sure if your addressing side boards or a raised cover, but this was how mine were done on my "new to me" 1930 82-B cc pickup. Hope they help with some ideas for you.
