No need for a different lower valance, but you will need to cut holes for the under rider support. The challenge I found was that the left pin seemed bent outward & sliding the valance in place required altering the hole cuts. Other issue is the bolts holding it in place are a bear to get to. Thin wall 1/2 " 1/4 drive works. If you have a need to replace the bolts, make them as short as possible.
