The center of the inner bumper bracket mounting hole to the center of the bumperette hole is about 2 7/8", the bumperette hole is a bit higher than the inner bracket hole so that's just the horizontal distance. The hole for the bumperette isn't perfectly in line with the center bump/feature of the turn signal lense, but based on the fade mark on my bumper the outer edge of the bumperette is almost perfectly in line with the outer edge of that center bump in the lense.
