In order to roll the front fenders, my liner had to be trimmed. Now I have a few concerns. If I drove in the rain, wouldn't water get in behind the head lights and to the connectors? Same thing would occur to the side markers as water would spray up behind your fenders. With a flashlight I can see straight to the underside of my headlights and sidemarkers. The gap from the trim isn't big but its there.

 

i dont know about others but when i rolled my fronts i kept the liner... i just slipped the liner behind the metal tabs that usually hold it in place and hammered the metal up against the fender squeezing the fender liner between the metal tabs and the actual fender.

 

my liner was trimmed too. so far no rain issues

 

As above, you can just slip the liner in between the lips of the guard..

 

I drove in the rain couple times with no fender liners and I didn't have any problems.
