So i test fitted a authentic TRD rear and its perfect. I notice there are 3 or 4 screw holes on the bottom and they seem to bolt onto the bumper. Since my car didnt come with the action pack, i will need to drill holes. Its pretty hard to drill holes if you cant see where youre drilling. Any ideas how to mount it? I can tap into the bumper fine with the screws in the wheel well. I was thinking of 3M automotive grade tape (the grey one) and tape the back.
