I didnt realize you had to trim the trim pieces. Is this the same for all the ditch brackets or where yours out of spec? I have a set coming this week (hopefully, since CBI hasnt responded to any of my emails).
The instructions tell you to remove them and leave them off once the ditch light brackets are installed. The ditch light brackets were fine, they just get in the way of the stock trim piece so I trimmed out a slot in the pieces so that I could re-install them with the brackets installed. IF you don't trim them then you have no choice but to leave them off...
