This 3-piece set of panels cover the the two vertical “b-pillars” behind the cab area as well as the storage area above the cab.
Note, the foam blocks installed by the factory at this location must be removed.
The panels can be attached to the van structure in a variety of ways. One approach is to drill holes into the van sheet metal and then attaching the panels using "automotive push clips" (similar to how the few factory-supplied panels in a Promaster are attached). Alternatively, you could secure the panels with self-tapping screws covered with screw caps. In both cases the push clips or screw head covers can be painted with SEM 15103 Color Coat paint to match the color of the panels.
Since this is a new product, we don't have any direct experience with painting the panels but we have heard that Dupli-Color Vinyl and Fabric spray paint has been used successfully on similar interior plastic panels. Another option that we recommend is upholstery with a fabric or marine vinyl.
