I will have to take better pics of the complete front view with them mounted, but this may help.
Essentially curved air dams in front of tire, like the Vibe, but a bit bigger left to right, and they come down a bit further.
ML350 - Look just in front of right front tire... I have seen them in person, they curve under the car and taper up a tad.
My Maxx splash shield mounting area... prior to install
Good luck, have fun, be safe.
