We have a 2016 308 BHTS that received some damage when a tire blew. This is on the "passenger" side of the trailer.

I have all the parts and am in the process of making the repairs. But I need to know how the fender skirt and bottom slide out cap meet up. By looking at pictures taken before the damage I see the skirt goes over the cap. But is the skirt notched or does in simply screw in place without regard to the thickness difference?
