Todd,
I just measured my original bumper clearance. From the floor to the bottom of my bumper is 13 and 1/4 inch. Also from the ground to the center of the bolts is 16 inches. I have a conceal panel between the bumber and the grill. (Do you want a photo?) I believe the reason was an early form of crumple zone. The impact would bend the bumper before the body or grill took damage.
Hope this helps.
Mitch
