I had my first incident with the gear select switch today, and my rear bumper paid the price as my trailer tongue punched through some plastic parts. . I need some help Identifying a part. I found the rear step pad part as (55112621AB), but I cannot find the part that the step pad snaps into. Pictures are below. Any help on a part number would be appreciated. It goes across the entire bumper and is a plastic honeycomb that attaches to the bumper via the torx bolts pictured.
