Bronx...depending how "big" the gap is...just buy some moulding protecter and apply it to the edge of the lip. I could be enough to fill in the gap if it isn't too much.
What I mean about moulding protector is that stuff manufacturers use when they have fender flares or OEM body kits. It acts as protection between whatever the fender flare or OEM body kit from rubbing or damaging the piece its attached to.
