I need a measurement from someone with an assembled gmc

[chewychevy67]

I was wondering if someone could tell me what the measurement Is from the front bumper center or from the outer bumper bolt square punched edge to the center of the inner headlight is? I am wanting to add fog lights to my bumper and I want the lights centered under the inner bulb. Picture s of the measurements could be helpful too. Pictures below show kind of what I need. Thanks in advance. Rod.
