The metal is 3/8" thick, 2" wide flat stock. The drilled holes are all centered on the 2" width. They have a diameter of 7/16" The measurements for the bottom pictured brakcet were taken from the far right end of the bracket working left to each hole's centre. The top pictured bracket I only measured the first hole from the left end. You can then bolt them together to get the holes all lined up. The bolts that went through the bumper also had spacers to act as a stop for the bracket on the rear side of the bumper.
