It's tough to tell but it looks like those dimples are about 10-11" apart.Those aren't starter holes for the license plate. Not U.S. plates, anyway, which are only 12" wide. The holes would need to be about 11" on center. Maybe you're looking at the Euro-spec Bronco.
Oh, I was looking at the grey part. It looked like there were starter holes at the 1/2" and 17 1/2" marks. Didn't even think to look up at the orange part. What were they trying to measure?What the heck are you talkin' about?
Those starter dimples are about 10" apart... they certainly are not further apart than 12"... which is how wide a plate is.
