I've noticed that some newer (above 09 or so?) Tacoma's have plastic plug inserts in the rectangle frame holes in the front wheel wells just behind the front tires. This seems like a good idea to keep the inside of the boxed frame dry while living in a north climate with road salt spray. If anyone would have a set of these for sale I'd be interested. Also, if someone could just pop one out and check to see if a part number is printed on the back, that would be great too. The stealership doesn't have a clue and can't find them in parts.
