idk i like the look of those they kinda look like bushwacker fender flares and mine are turning and odd white and grey milky color and it is starting to look gross
I believe the entire front fenders will fit (but you would have a tough time finding the right color), but as STL said, they wont match up with the holes you currently have in your fenders if you get just the flares.
For the back, you would only be able to get the flares unless you were to get a whole new bed.
