You may not have to, it really depends on the wheels width and backspacing. IF you already got them, put one on and test fit it.
I had the same issue but its really not hacking.,,,Its a seam that is about 1" high and if you tap it lightly with a rubber mallet or Ball/Peen it "rolls" right at the botttom of the 1" and makes an "L" shape so instaed of looking this"/" it ends up looking like this "L". Not a big deal at all. It rolls on a natural line an looks great. Get a can spray body underliner/undercoating by permatex and spray the crease line and you will never know you were there...
