The stock fogs left in the stock locations will fit behind the TRD front bumper. However most people think they are too small for the bumper and buy bigger ones to fit in the outer holes of the TRD front.
You can fit the bumper fine with the stock fogs, since they'll be sticking out of the two inner holes of the bumper. People like myself switched them out since the foglights for the TRD bumper are supose to go in the outter circle cutouts that are 4inches in diameter.
It looked ugly with the stock fogs in my opinion. An easy affordable fix is the 40 dollar fogs from Walmart.
