cool good to know well i went out to home depot and picked up some rubber weather stripping to close up my gap i'm just going to glue it on to my bumper with some silicone/weather resistant adhesive, i figure between being compress by the bumper and my truck with teh adhesive it should stay put, i do forsee the need to replace it every year or more, i may go with a full on rubber threshold in the future, that said i'm going to try this first, also on a side not you don't want teh bumper flush incase if you hit anything it gives teh bumper room to move a bit before it starts smashing into body panels, so i was thinking that leaving the gap and filling it with some sort of rubber would look good for appearances and also provide some usable space incase of an accident.
