You may also need to drill holes in all the gaurds to attach flares, the female side of the clip that sits into the gaurd holes is a oval shape not just round, so drilling holes would be a pain, Sikaflex may work but theres not much of a lip on the flare to work with.

To do it right, the front and rear bumber bars will need to be wider to join up with the flares as they would from factory.



As you said, you could always just put those rubber flares on , cheap and easy, and it can look ok.
