Bumper Guards: is there a L and R?

[D'Monsta]

Just bought a repro pair from The Truck Shop here in Concord NC. I was concerned about the new ones not matching the bumper contour so the guy let me bring one out to the truck. Matches great.. They are chrome, so I'll have to scuff and paint them of course, and repaint my bumper at the same time.. Can someone add measurements to the template image? Distance from edge of paper to upper and lower lines, then distances between holes, etc.. I'll make one based on those measurements to use with mine. The guards do not come with a template.. Just mounting hardware
