I suspect these may be a perfect fit for fleetside beds. Unfortunately, they’re undersized for a stepside and pre-tapped holes to attach to fleetside mounting points can’t be used as they don’t exist on a stepside (single bolt at the top of the wheel well which is much higher than these are molded). They could look great, but are going to need some tinkering to install them neatly/securely (slightly smaller outer circumference than original, so not all push pin holes can be used).
