I went ahead and did my homework, since I wanted a rear bumper protector to cover up my nicks and such on my rear bumper. I decided that I wanted to go with the OEM 09-13 Matrix style protector since it looks the best (Based on pictures I found online). With further investigation I found out that the Bushwacker part and the OEM Toyota part ARE EXACTLY THE SAME they literally are using the same pictures in both installation guides! So this leads me to believe that Bushwacker is the OEM supplier of this particular part to Toyota, I ended up getting the Toyota part because it was cheaper than the Bushwacker part.
Bushwacker Part Number: 34011 (http://www.carid.com/images/bushwacker/ ... ctions.pdf" onclick="window.open(this.href);return false;)
OEM Toyota Part Number: 00016-12828 (http://www.trdsparks.com/install/00016-12828inst.pdf" onclick="window.open(this.href);return false;)
Hope this helps!
