Seen a few threads around misaligned front bumpers on the ISF. Was there ever a fix besides replacing the bumper? I do see a small bolt sitting on the underside wondering if tightening that will bring the gap together. Attached is the gap and it’s only on the driver side

 

Are all the tabs intact?

 

I had the same problem on my F. Turned out to be a broken plastic tab. Once I replaced the tab, the bumper fitment was spot on.
