What the Heck is This Called? '72 D200

Apologies if this is the wrong place to post this but I'm having one heck of a time finding a proper name for these rubber-ish mats as I go through the the engine bay of my '72 D200. If anyone can give me a proper name and/or a place to pick up some new or at lease decent shape ones I would be very appreciative. They sit between the inner wheel wells and the engine block.

officially called by the factory as inner fender to frame splash guards. At least that's what they are in my 78 chassis manual on my w200. Get the clips too if you can.
