im not sure how far off it is it looks to be about 3 inches or so farther back. i will try and get some pictures. i dont have the bed on so i cant tell how it will look, but i put a pole across my bed and marked out where the wheel opening is and it doesnt look like it will hit the tire at all but the tire will be closer to the rear of the fender by a couple inches. i havent talked to anyone about it but i hope they will help me. im sure they dont work with this year truck but the guy that i talked to told me that this would work no problem so i feel that its his responsibility. i'll keep ya posted thanks for the input.
