LOOK! You can see asphalt between the bumper and valance before!
Gap?
Slight trimming was required in the slots that the bumper tabs go in. A rotary tool comes in handy. Another area that I had to trim due to the 1" tuck is at the very center/top of the spoiler. It interferes with the vertical hood latch bar on the core support. If you do not tuck your bumper you do not have to trim the center.
Notice above. this is looking directly up from the bottom of the radiator core support and radiator. Look past the bracket.
The spoiler had to be contoured around the hood latch bar with the 1" bumper tuck. Bad pic because the bracket is covering what I'm talking about but you can see the trimming on the top flange of the spoiler between the bolts that hold the support bar.
