Well this is a possible solution... but this is made by me. I didn't get the measurements exactly correct for what I wanted so I may take another shot at it, but sewing is not a strong point (or my sewing machine, yes mine not the DW, is not very strong).
This was done to keep the sun off the air bags and rubber components.
