I was lookin at buyin a set of nerf bars with the heal gaurds molded into the nerf bar it self. i was wonderin how they look as opposed to the stock black heel gaurds. i noticed that the stock gaurds are shapled like the rear fender and was wonderin if the AC heal guard are molded like the stock ones. thanks for any help. also, if the AC bars are not molded like the rear fender, can i leave the stock heal gaurds on if i buy nerf bars. thanks for the help.
